1. Deliverance from the bonds of sin, death, and the devil:
  • By His suffering and death on the Cross Christ paid the price for our sins. By His resurrection He delivered us from the bonds of sin, death, and the devil, as is said: "... so that through death he might destroy the one who has the power of death, that is, the devil, and free those who all their lives were held in slavery by the fear of death."  (Heb. 2:14-15, cf. Rom. 8:21).
2. Eternal life for all believers:
  • The resurrection of Jesus destroyed death and allowed those who follow Jesus to have eternal life like him: ”So that as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life." (Rom 6:4), and “for as all die in Adam, so all will be made alive in Christ.” (1 Cor. 15:22).
3. New dignity of God’s children and partakers of His Divine Nature:
  • The justification brought about by Christ’s resurrection consists not only in victory over the death, but also in a new participation in new grace - it brings about filial adoption so that men become Christ's brethren and adopted children of God (Rom. 8:21). It also makes us sharers in divine nature: “But God, who is rich in mercy, out of the great love with which he loved us even when we were dead through our trespasses, made us alive together with Christ - by grace you have been saved - and raised us up with him and seated us with him in the heavenly places in Christ Jesus.“ (Eph. 2:4-5, cf. 1 Pet 1:3).
