The Bible says that God’s law obligates us to obey it completely. But God knows there is no way that we can do that. And since the punishment for failing to obey is separation from God, He had to provide a way to overcome this barrier. God’s solution was to simply release us from the requirements of the law. Freedom from law means that punishment for breaking it is no longer charged against us.
In Christ we are no longer subject to the realm of the flesh, even though our flesh continues to oppress us. Romans 8 says: “You are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you. If Christ is in you, though the body is dead because of sin, yet the spirit is alive because of righteousness.” Unbelievable as it may seem: “There is now no condemnation for those who are in Christ Jesus.”
