I once believed in fighting the devil. But mercifully over time as God shined more light into my heart, I learned to "resist the devil" by "yielding to the Spirit" of God. When you yield to the Holy Spirit, you automatically resist the devil. The Son of God became the son of man and gave His life willingly.
Heb 2:14 “....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;
The devil “had” the power of death. It does not say the devil HAS it.
In the “now” of God, which is “right here, right now”, the light of revelation makes me see that the devil lost his power. Jesus says, “All power is given unto me….” He said, “All authority has been given to Me in heaven and on earth.” (Matt 28:18) How much is all? 100%. How much power has the devil got? He only has what you and I give him back again. Because Jesus took it from him. We give him back the power through fear.
The only hope of the enemy of our faith is deception. His power is gone but not his wiles. Beware of the “wiles of the devil.” (Ephesians 6:11) The devil uses schemes, or wiles, to deceive us, to get us to believe lies about ourselves or others. This gives him back the power that Jesus took from him at Calvary. .......Let God be true… cast down the vain imaginations of a religious mind full of works and self effort and begin to cultivate a “throne relationship”. That’s where "ALL" authority is. Its in a “finished work” that allows us to enter into a rest … seated with our Lord in “heavenly places”
