The book “My Testimony” is a proof of Dr. Kalu Oji’s living experience of the mercy and power of God. It is the reality of God in addition to the efficacy of the word of God. According to Dr. Oji, preaching the word of God is not simply story telling. For one’s preaching to effect change in others, it must come from the overflow of one’s personal experience with our LORD Jesus Christ backed by His word, as a result of intimate personal fellowship with the Spirit of the Living God followed by the demonstration of God’s power. Glory to God, Alleluia!!!
