Through the blood of Jesus, our sins have been pardoned/forgiven. So likewise, Jesus's blood has made intercession for the transgressors - those who break away from just authority, trespassers, and in rebellion to the laws of God.
Doing the will of God can be summed up in one word… OBEDIENCE! When you obey God's word, you are doing the will of GOD. Your love for JESUS will cause you to obey his word John 14:15 (If ye love me, keep my commandments.)
