We must be doers of the word of God and not only hearers of it. V. 22 "But be doers of the word, and not only hearers." That is our duty, very simple. God has given us his word to instruct us, first of all, on what we must believe to be saved. But he has also given us his word to teach us how to live the Christian life after being saved.
Brothers, the Christian life is a life to be lived. And everything that is taught and everything we try to learn is with a view to putting it into practice.
