The only one who wants man’s downfall and is an enemy to man is the devil. He is man’s real enemy who seeks to destroy us by any means necessary but unfortunately many do not see it this way.
Jesus said in John 10:10 “The thief comes to steal, kill and to destroy.” That is and has been His agenda, to steal the life Christ has for us, to kill destinies and destroy man utterly completely. John 3:8 also states why Jesus came, it says “for this purpose the Son of God was manifested, that He might destroy the works of the devil.” That is why during Jesus’ earthly ministry all He did was heal the sick, cast out demons, raise the dead, preach and teach the Kingdom of God and repentance. Anything contrary to this is the work of the devil. Sickness, demonic oppression, failure, stagnancy, bondage, etc all comes from the devil. Jesus furthermore stated that evil comes from the devil. (Mark 7:32-35, Luke 4:18-21, Mark 5:8, Acts 10:38).
