The security of the believer is the objective reality of what God has done to save believers and keep them saved. It is different from the believer’s assurance, which is his subjective experience of his salvation. A believer’s security is unchanging. Despite what he feels about his salvation, once his name has been penned in the Lamb’s Book of Life, his salvation is eternally secured.
Scripture offers many evidences of the believer’s security:
- Security means we cannot do anything to corrupt or lose our salvation and no one else can remove us from the salvation of God (Jn. 10:28)
- The sovereign purpose of God makes us secure (Rom. 8:28-30; Eph. 1:4, 11-12)
- The power of God keeps us secure (John 10:27-29; Rom. 8:31-39; 1 Pt. 1:3-5)
- Security is a demonstration of the love of God (Rom 5:8-9)
- Security is produced by the justification in Christ (Rom. 8:1; Heb. 10:14)
- The intercession of Christ is a further gift of the believer’s security (1 Jn. 2:1; Heb. 7:25)
- Security is guaranteed by the Holy Spirit —
- His permanent indwelling (Jn. 14:16-17; Eph. 1:13; 4:30)
- His sealing unto the day of redemption (Eph. 4:30)
- His baptism of the believer into the body of Christ (1 Cor. 12:13)
- Security results in Christ presenting us faultless before himself (Jude 24; Phil. 1:6; 1 Pt. 1:5; 2 Tim. 1:12)
Eternal life is eternal because it is based on the eternal justifying work of Christ and His imputed righteousness. A believer is secure not because of what he has done to keep himself in God’s love but because of what Christ the Righteous has done to save and keep the believer in God’s love.
