The centerpiece of this ministry is, without a doubt, the revelatory Gospel preaching, punctuated by the lively delivery style that emanates from Willis' Pentecostal background. A hearty Amen fits well in this preacher's sermon. Scores of people --- young and old, rich and poor, urbanites and country folk, ---have found God through his heartfelt delivery of the Word of God.
Worship and the Word are the key elements in taking the vibrant ministry of Dr. Andrew J. Willis to camp meetings, conferences, crusades and extended revival meetings around the world. Whether it is here, in these various venues or the pulpit of The River of Life Church; he is known simply as---"The Evangelist"
