And this we will do if God permits. (6:3)
The writer will proceed to discuss the more advanced matters, and thus encourages his readers toward maturity. However, he recognizes the necessity of God’s involvement if his task is to be successful. If God permits is more than a pious sentiment. It is an acknowledgment that only God can change the course of a man’s life when it is going in the opposite direction.
