Christianity is God’s call to man to a life of glory, success, health, peace, joy and unending streams of victory. The Bible says “For this purpose the Son of God was manifested, that He might destroy the works of the devil” (1 John 3:8). Jesus has already destroyed the works of the devil, “Forasmuch then as the children are partakers of flesh and blood, he also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil” (Hebrews 2:14). Believing in Jesus Christ means Satan’s power over your life is immediately broken, and nothing in this world can successfully stand against you, for "…greater is he that is in you, than he that is in the world" (1 John 4:4).
In Christianity we are not trying to overcome the Devil, Jesus has already defeated him and gave us the victory. “But thanks be to God, which giveth us the victory through our Lord Jesus Christ” (1 Corinthians 15:57). God the Father has already delivered us from the powers of darkness, and translated us into the Kingdom of his dear Son, (Colossians 1:13 ). Satan is a weak Devil, Whether he likes it or not his throne has been put under My feet, his power is powerless to a child of God, Hallelujah. In all these things we are more than conquerors through him that loved us (Romans 8:37)"…we are more than conquerors…." means victory over the adversary is an old conclusion, we've gone past the stage of celebrating our victory in Christ" God has given us a life of peace, strength, health and prosperity; the victorious life, Hallelujah.
