When Jesus atoned for all sin, this means that the sin debt was paid, at least for those who will believe, which then gives the Holy Spirit the latitude to work powerfully within our lives. The power is in the Holy Spirit, Who manifests such on our behalf, at least if our Faith is correctly placed in Christ and the Cross. The Cross is what afforded this.
Whenever we preach the Cross, and when individuals believe what we preach, the Holy Spirit can then exercise His Almighty Power on their behalf, for He is God; then sin, in all of its forms, can be overcome; then every bondage can be broken.
The Bible says in 2 Cor. 13:4, that Jesus was crucified through weakness. Which it had to be because God's Grace is only made perfect in weakness. Therefore, through weakness, Jesus was crucified that He may taste death by the Grace of God (Hebrews 2:9). As Children of God, we get to taste that same death in Christ daily by picking up our own cross (which can only be done by trusting His Grace which is made perfect through our weakness by placing and maintaining our Faith exclusively in Christ and His Finished Work at Calvary Cross where the victory was won) and walking with Christ in the newness of life (His victory). Rom. 6:3-5, Rom. 8:17, Gal. 2:20-21, 2 Cor. 4:11, 2 Cor. 12:9-10, 2 Cor. 13:4, Hebrews 2:9
The fruit that a Child of God bears comes only by Righteousness which is by Grace (Gal. 2:21). Grace only comes through the weakness and death of Christ (2 Cor. 12:9-10). Therefore, Grace is only made perfect through weakness (not our flesh); but only by trusting and placing and maintaining our Faith exclusively in Christ and the Cross. This is the only way Grace flows in a Child of God's life. This Child of God is considered weak, humble, and broken before God. (THE BEATITUDES MATTHEW 5)
