A stream passes through a forest. A couple are carrying a canoe through the forest with great difficulty until they find the stream. Then, they are liberated by the stream from the difficulties of the forest. If they become liberated from the banks of the stream, or the direction of the stream, they have lost their freedom from the forest.
A train without tracks limiting its path has no freedom to travel.
Therefore, no condemnation now exists for those in Christ Jesus, because the Spirit’s law of life in Christ Jesus has set you free from the law of sin and of death. What the law could not do since it was limited by the flesh, God did. He condemned sin in the flesh by sending His own Son in flesh like ours under sin’s domain, and as a sin offering, in order that the law’s requirement would be accomplished in us who do not walk according to the flesh but according to the Spirit.
