The majority of believers do not know how to deal with guilt. We have been delivered from guilt but we must appropriate the release of its hold over us through the truth and power of Christ Jesus. Part of evil is being manipulated by guilt. Satan uses guilt to keep the believer from growing near to grace. Grace being the means by which God reveals Himself to us.
Grace is also that by which Bible doctrine is illuminated.
Many believers think that they are able to discern Satan's policy of evil and God's policy of grace. In reality they cannot even distinguish between divine good and human good and evil. God's policy always offers a way of restoration, His policy offers grace, forgiveness and acceptance. Here the woman mentioned who was attending to Jesus knows well the forgiveness of God and she was wholly grateful for it. This emphasizes the fact that legalistic people are always users.
