"God cannot do through a man what he does not have in him, or what a man has not allowed God to do in him." These words from the author, Z.T. Fomum, demonstrate that anyone who wants to walk with and serve God must deal with his heart. God seeks the inner temple, the heart of the believer, to make his home there. Therefore, God's first call to a person is not first of all the call to service. It is the call to know Him deeply and to love Him in a supreme way. These are people carried away by the knowledge and love of God who can go and serve Him. A heart filled with love for the world and the things of the world cannot serve Him. The service of such a man will be rejected. It is in these very clear and compelling terms that the author unloads his onus. As you read this book, you will certainly discover the state of your heart and you will be able to work to present to the Lord a heart qualified to worship and serve Him.
