All believers do the will of God! And His will is... Be Perfect! .... Look here...
For whosoever shall do the will of my Father which is in heaven, the same is my brother, and sister, and mother.
What an awesome God this is to make family members of once sinners! Only the grace of God can be that powerful! Praise the Name of Jesus Christ. He can and will give NEW Spirit to all who will do the will of Father! Lord spare me some of Your Spirit, AMEN!
