Assurance of Salvation in Everyday Christian Life

Assurance of salvation refers to a believer's confidence that they are in a state of grace and will receive eternal life [1, 2]. This conviction is rooted in faith and is understood as a gift from God, not a human achievement [8]. The New Testament frequently discusses this concept, with terms like "full assurance of faith" (Hebrews 10:22) and "full assurance of understanding" (Colossians 2:2) appearing in the biblical text [1]. The Greek word plerophoria, translated as "full assurance," implies a complete conviction that leaves no room for doubt [1].

The foundation of assurance is God's work through Christ. Salvation itself is "of God" and "by Christ alone" [3]. The resurrection of Jesus is presented as God's pledge that his revelation is true and worthy of acceptance [1]. Believers are "made alive together with Christ" and share in his resurrection, both now and in the future [7, 12]. This union with Christ means that believers are no longer strangers but are fully accepted into God's family [10].

Assurance is produced by faith, as seen in passages like Ephesians 3:12 and Hebrews 10:22 [2]. It is also made full by hope (Hebrews 6:11, 19) and confirmed by love (1 John 3:14, 19; 4:18) [2]. The effect of righteousness also contributes to assurance (Isaiah 32:17) [2]. The understanding of the gospel brings abundant assurance (Colossians 2:2; 1 Thessalonians 1:5) [2].

Scripture indicates that saints are privileged to have assurance concerning various aspects of their spiritual state:

Salvation is not earned by human actions but is a result of God's grace and mercy alone [8]. Good works are understood as the result of salvation, not its cause [9]. God creates believers anew in Christ Jesus, enabling them to do the good things he planned [9]. The Holy Spirit works through a transformed heart to produce a good life, expressing God's life within the believer [9, 13]. This transformation involves putting off the "old sinful nature" and putting on a "new nature" in Christ [11].

The concept of eternal life, which is the ultimate outcome of salvation, is frequently mentioned in the New Testament [5]. It is described as the "whole future of the redeemed" and is contrasted with "eternal punishment" [5]. This newness of life derived from Christ is the beginning of eternal life [5]. Adam Clarke notes that a person who is saved is drawn by the Father, hears his instructions, accepts salvation, is given to Christ for justification by faith, is nourished by the bread of life, perseveres in faith, is not lost, is raised at the last day, and partakes in eternal life [15]. Christ is called "our salvation" because he is the author of salvation for those who believe [16]. The gospel itself is described as "the power of God unto salvation to every one that believeth" (Romans 1:16, KJV) [6].

Believers are encouraged to wait upon God for salvation, guidance, and the fulfillment of his promises [4]. This waiting is an act of faith and hope, anticipating the coming of Christ [4]. Even in adversities, believers are called to give thanks to God and the Father through the Lord Jesus Christ, recognizing God as the source of every blessing [14].

Easton's Bible Dictionary “Easton's Bible Dictionary: Assurance — The resurrection of Jesus (Acts 17:31) is the "assurance" (Gr. pistis, generally rendered "faith") or pledge God has given that his revelation is true and worthy of acceptance. The "full assurance [Gr. plerophoria, full bearing'] of faith" (Heb. 10:22) is a fulness of faith in God which leaves no room for doubt. The "full assurance of understanding" (Col. 2:2) is an entire unwavering conviction of the truth of the declarations of Scripture, a joyful steadfastness on the part of any one of conviction that he has grasped the very truth.

It occurs frequently in the New Testament (Matt. 7:14; 18:8, 9; Luke 10:28; comp. 18:18). It comprises the whole future of the redeemed (Luke 16:9), and is opposed to "eternal punishment" (Matt. 19:29; 25:46). It is the final reward and glory into which the children of God enter (1 Tim. 6:12, 19; Rom. 6:22; Gal. 6:8; 1 Tim. 1:16; Rom. 5:21); their Sabbath of rest (Heb. 4:9; comp. 12:22).

Ephesians (Protestant academic) “Tyndale House on Ephesians 2:5: 2:5 gave us life when he raised Christ from the dead (literally made us alive together with Christ): Joined with Christ, believers share in his resurrection, now and in the future (see 2:6; Rom 6:4-14; Col 3:1-4). • It is only by God’s grace that you have been saved: See Eph 1:2; 2:8-9.”
  8. Titus (Protestant academic) “Tyndale House on Titus 3:5: 3:5 not because . . . but because: The contrast is between human actions that might be thought to merit salvation and God’s grace (see Gal 2:16). Salvation is through faith in God’s mercy alone (Eph 2:8). • He washed away our sins, giving us a new birth: See Ezek 16:9; John 3:1-15; Eph 5:26; Heb 10:22; 2 Pet 1:9. • and new life through the Holy Spirit: This signifies a complete departure from the life of sin and death and a transfer into the realm of life and purity (see also Rom 12:2; 2 Cor 5:17; Col 3:10).”
  9. Ephesians (Protestant academic) “Tyndale House on Ephesians 2:10: 2:10 He has created us anew in Christ Jesus, so we can do the good things he planned for us: Good works are the result, not the cause, of salvation.

Believers strip off their old life and put on Christ’s new life, allowing him to be Lord and to guide the way they live.”
  12. Ephesians (Protestant academic) “Tyndale House on Ephesians 2:6: 2:6 united with Christ Jesus: Because of this union, believers share God’s glory and blessings, and experience resurrection both now and in the future (see Rom 6:4-14; Col 2:12-13; 3:1-4).”
  13. Ephesians (Protestant academic) “Tyndale House on Ephesians 4:24: 4:24 A believer has a new nature: God’s Spirit expresses his life within the believer (see Col 3:10; cp. Gen 1:26; Rom 12:1-2; Gal 5:22-23). The transforming work of God’s Spirit is part of the gift of salvation (Eph 2:8-10).”

Our blessed Lord recapitulates here what he had said in the preceding discourse. The person who is saved is, 1. drawn by the Father; 2. hears his instructions; 3. accepts the salvation offered; 4. is given to Christ Jesus, that he may be justified by faith; 5. is nourished by the bread of life; 6. perseveres in the faith; 7. is not lost, but is raised up at the last day; and 8. is made a partaker of eternal life.”
  16. Luke (Methodist/Wesleyan) “Adam Clarke on Luke 2:30: Thy salvation - That Savior which it became the goodness of God to bestow upon man, and which the necessities of the human race required.
