Soteriology Lesson 31 - Assurance of Salvation

Thinking on Scripture with Dr. Steven R. Cook

At the moment of faith in Christ, we have eternal life. This is a fact, even if we don’t fully understand it. In truth, most people will not understand what they have from God or find assurance of their salvation until they’ve studied God’s Word and learned to live by faith. Doctrinal ignorance and/or false teaching will lead to fear and doubt. For those who have trusted Christ as their Savior, subsequent knowledge of God’s Word and trust in it will yield assurance of their salvation. And, as one advances spiritually, there will also be a noticeable change within, and this too may provide a subjective assurance of salvation.

Objective Assurance of Salvation

The Bible reveals God is absolutely righteous and set apart from all that is sinful (Psa 11:7; 99:9; Hab 1:13; 1 John 1:5) and He hates and condemns sin (Deut 25:16; Psa 5:5; 45:7; Prov 8:13; 15:9, 26; 20:9; Zech 8:17; Rom 1:18; Col 3:6; Heb 1:9). The problem for us is that all mankind is sinful (Gen 6:5; 8:21; 1 Ki 8:46; Psa 143:2; Eccl 7:20; Isa 59:2; 64:6; Jer 17:9; Rom 3:10; 3:23; Eph 2:1-2; 1 John 1:8, 10). Not only are we sinful, but our good works have no saving merit (Rom 4:4-5; Gal 2:16; Eph 2:8-9; Tit 3:5). Our salvation was accomplished 100% by Jesus who died on the cross for our sins. Salvation is never what we do for God, but what He’s done for us at the cross (Rom 5:8; 6:10; 1 Cor 15:3-4; 1 Pet 3:18). God offers to justify and save us freely as a gift, totally apart from any good works we may perform (Rom 3:24, 28, 4:5; Gal 2:16; Eph 2:8-9; Tit 3:5; 1 Pet 3:18). God’s salvation comes to us who have trusted in Christ as our Savior (John 3:15-18; 6:40; 10:28; 11:25; 14:6; Acts 4:12; 16:31; 1 John 5:12). Salvation means we have forgiveness of sins (Eph 1:7), the gift of righteousness (Rom 5:17; 2 Cor 5:21; Phil 3:9), eternal life (John 10:28), are part of the family of God (Gal 3:26; 1 John 3:1), are blessed with many spiritual blessings (Eph 1:3), and will never face condemnation (Rom 8:1, 33).

When we understand these truths by studying Scripture and accept them by faith, we have assurance of our salvation because we trust in God and His Word (Psa 119:160; John 17:17). The apostle Paul wrote, “I know whom I have believed and I am convinced that He is able to guard what I have entrusted to Him until that day” (2 Tim 1:12). The apostle John wrote, “God has given us eternal life, and this life is in His Son. He who has the Son has the life; he who does not have the Son of God does not have the life” (1 John 5:11-12). The assurance of salvation does not come by looking to ourselves, but to the One who saved us. John also wrote, “These things I have written to you who believe in the name of the Son of God, so that you may know that you have eternal life” (1 John 5:13). Assurance of salvation is not a guessing game for those who have trusted in Jesus as their Savior, but is a confidence that is rooted in the revelation of God’s Word. For those of us who have trusted in Jesus as our Savior—believing He died for our sins, was buried, and raised again on the third day—we have eternal life. According to Zane Hodges, “It should be said here that all true assurance of salvation and eternal life must rest on the ‘testimony of God,’ for only that testimony has full reliability and solidity.”[1]

What Calvinists and Arminians Generally Believe

Arminians are those who believe they are eternally secure in Christ, as long as they remain faithful in their walk with God. Like Catholics, they believe faith + works = salvation. They believe their salvation can be lost due to intentional, egregious, ongoing sin; therefore, they cannot have assurance of salvation because there’s always the chance they may turn away from God and forfeit their salvation. This stands in contrast to the Calvinistic doctrine of perseverance of the saints, which teaches that those whom God has chosen will persevere in faith until the end.

Calvinists believe God gives His elect a special kind of faith that guarantees they will persevere to the end of their lives and be saved eternally; however, knowing they are among the elect is always a question in their minds that cannot be finally answered until they die. If they have persevered until the end, not having denied the Lord, and continued in good works, then they can know they were among the elect. If they fall into serious and prolonged sin, especially to the end of their lives, it strongly argues they were not among the elect who are said to persevere to the end. Kenneth D. Keathley notes, “Arminians know they are saved but are afraid they cannot keep it, while Calvinists know they cannot lose their salvation but are afraid they do not have it.”[2] Norman Geisler correctly notes:

• "Arminians and strong Calvinists have much in common on this issue. Both assert that professing believers living in gross, unrepentant sin are not truly saved. Both insist that a person cannot be living in serious sin at the end of his life if he is truly saved. And both maintain that no one living in grave sin can be sure of his salvation."[3]

Though Christians may, to some degree, advance spiritually by learning and living God’s Word, and bear the fruit of the Spirit in their lives, this will never be consistent, because the taint of sin is also present in the life of every Christian, and this to varying degrees. Christians are never free from sin (1 John 1:8, 10), and God never promises to make us completely sinless during our time on earth, so consistency of performance is lacking. Because of our imperfect knowledge and imperfect life, our ability to analyze ourselves accurately will not always be consistent. John Walvoord notes:

• "The difficulty is that human experience may be far from a norm, may be inaccurately analyzed, and may be made the basis of an induction which in the last analysis is based only on fragmentary evidence…The only sure basis for salvation is the promise of God in the inspired Word of God which properly accepted by faith gives validity to assurance. One clear promise sustained by “Thus saith the Lord” is better than a thousand testimonies of human conviction without a specific ground. A proper doctrine of assurance of salvation is therefore inseparable from a belief in the inspired Word of God."[4]

The Word of God is the objective basis for what we believe, and our focus should always be on learning and living His Word so that we can expunge any false ideas and properly calibrate our thinking to align with His divine revelation. Jesus said we have “eternal life…and will never perish” (John 10:28); therefore, there is no danger of us losing our salvation, for there is “no condemnation for those who are in Christ Jesus” (Rom 8:1), and “Who will bring a charge against God’s elect? God is the one who justifies” (Rom 8:33). The matter of our eternal destiny was settled at the cross when Jesus paid the penalty for all our sins. And Jesus’ work on the cross was perfectly applied to us at the moment we trusted in Him as our Savior.[5]

Subjective Assurance of Salvation

Christians who are advancing spiritually may enjoy a subjective assurance of their salvation. Paul wrote, “The Spirit Himself testifies with our spirit that we are children of God” (Rom 8:16). According to William MacDonald, “The Spirit Himself bears witness with the believer’s spirit that he is a member of God’s family. He does it primarily through the Word of God. As a Christian reads the Bible, the Spirit confirms the truth that, because he has trusted the Savior, he is now a child of God.”[6] This experience is valid only for believers who are in submission to God (Rom 12:1-2), learning and living Scripture (2 Tim 3:16-17; 1 Pet 2:2), walking by faith (2 Cor 5:7; Heb 10:38; 11:6), and advancing to spiritual maturity (Heb 6:1).

As believers, we have been “born again” (1 Pet 1:23), “made alive” spiritually (1 Cor 15:22), and are a “new creature” in Christ Jesus (2 Cor 5:17). At the moment of salvation, God the Holy Spirit indwells us and gives us a new nature that, for the first time in our lives, has the capacity and desire to obey God. Paul wrote of his new nature in Christ when he said, “I joyfully concur with the law of God in the inner man” (Rom 7:22). Since we have the Spirit within us, as well as new spiritual life, it is natural to expect there will be some change in attitude and behavior. The degree to which this change occurs, in part, depends on our staying positive to the Lord. According to John Walvoord adds:

• "The ground of assurance as stated in Scripture is something more than an intellectual comprehension of the theology of salvation and more than a conviction that the terms of salvation have been met. Scriptures make plain that there is a corresponding experience of transformation which attends the work of salvation in a believer. Some aspects of this are nonexperimental, but the new life in Christ is manifested in many ways. The believer in Christ possesses eternal life and a new divine nature which tends to change his whole viewpoint. He is indeed “a new creature: the old things are passed away; behold, they are become new” (2 Cor 5:17). The believer in Christ is indwelt by the Spirit of God, which opens a whole new field of spiritual experience. He now knows what it is to have fellowship with his heavenly Father and with His Savior the Lord Jesus Christ. His eyes are opened to spiritual truth, and the Scriptures take on a true living character as the Spirit of God illuminates the written Word. He experiences a new relationship to other believers as he is bound to them by ties of love and common faith and life. The believer is relieved from the load of condemnation for sin and experiences hope and peace such as is impossible for the unbeliever. His experiences include deliverance from the power of sin and from opposition of Satan. He enters into the joy of intercessory prayer and experiences answers to prayer. The new life in Christ, therefore, provides a satisfying and Biblical new experience which is a confirming evidence of the fact of his salvation and a vital and true basis for assurance."[7]

As Christians, our assurance of eternal life is, first and foremost, based on the salvific work of Jesus on the cross (Acts 4:12; Rom 5:8; 1 Cor 15:3-4), and the revelation of Scripture that we, who have trusted in Christ as our Savior (Acts 4:12, 16:31), “may know that [we] have eternal life” (1 John 5:13). This assurance is objective and constant, because God’s Word is sure and does not change.

[5] The Bible reveals that when we sin, we are walking in darkness and have broken fellowship with God (1 John 1:5-6), and stifled the work of the Holy Spirit who dwells within us (Eph 4:30; 1 Th 5:19). If we continue in sin, or leave our sin unconfessed, we are in real danger of divine discipline from God (Psa 32:3-4; Heb 12:5-11; 1 John 5:16-17; cf. Dan 4:37), which can eventuate in physical death (1 John 5:16; cf., Lev 10:1-2; Acts 5:3-5; 1 Cor 11:30), and the loss of eternal rewards (1 Cor 3:10-15; 2 John 1:8). If we confess our sin directly to God, He will immediately forgive it and restore us to fellowship (1 John 1:9; cf. Psa 32:5). Being in fellowship with God means learning and living His Word (2 Tim 2:15; 3:16-17; 1 Pet 2:2), walking by faith (2 Cor 5:7; Heb 10:38; 11:6), being honest with Him about our sin (1 John 1:8, 10), and coming before His “throne of grace” (Heb 4:16) in transparent humility and confessing it in order to be forgiven (1 John 1:9; cf. Heb. 4:16). God is faithful and just to forgive us our sins every time we confess them because of the atoning work of Christ who shed His blood on the cross for us (1 John 1:9; 2:1-2).
