God put man in charge of the earth. Adam was deceived by satan out of that position of authority . Adam"s descendants continued to follow Adam's example and handing authority to Satan through believing his lies and obeying him by sinning. .Jesus came as a human and never allowed Satan to deceive Him out of His birthright. Jesus kept His authority over satan. By receiving forgiveness for our sins we can stand in our birthright authority in Christ, Jesus has won for us our original prefall authority over satan, but we must exercise that authority according to God"s design, which is that we submit to God and then we resist the devil with God's truth until the devil flees. We are not told to ask God to defeat the devil for us. We are told to engage the devil ourselves with faith that Jesus backing us up,
So many Christians live in constant defeat because we are waiting for someone else (even God) to rescue us from the devil's attacks and snares, asking someone else to do what God told us to do, when we should be worshipping and praising God that He has put us in authority over the devils, and attacking the devil back with Jesus truth in our mouth and in our deeds and driving satan out in Jesus' authority..
