Separated, Called and Revealed
There is an interesting principle that the apostle Paul brings out in Galatians. Paul says he was separated from his mother's womb. "But when it pleased God, who separated me from my mother's womb, and called me by his grace" (Galatians 1:15). He was separated into God's grace. He used the same phrase as the Pharisees. A Pharisee can literally quote 435 laws of God, and know all the smallest details of the law. He was the same unto grace that the Pharisees were to the law. Nothing was able to turn him from grace.
We need to mark off a boundary line by placing a limitation on our past. To the extent we allow this to happen, the enemy will be less likely to pull us away. Satan tries to get us to be re-oriented to the past, but we have been severed just as Paul was. We are now called unto God's grace. "Before I formed thee in the belly I knew thee; and before thou camest forth out of the womb I sanctified thee" (Jeremiah 1:5a).
God has set us apart unto grace. We have been severed from anything of the old life, including condemnation. As we implement the fact that we are separated from our old life, grace will in turn be revealed to us and we will be able to reveal it to others.
