We must learn to trust the power of God’s Word to convince, convert, and change lives (Rom. 1:16; 1 Cor. 1:18; 1 Pet. 1:23)...without the help of our man-made systems… We must be so convinced, or we will be tempted to add things to the preaching of the Word to secure greater commitments… Here is the real question: How powerful is the Word of God? Can it change men from sinners into saints without the use of an altar call? Will it convict and convert (as God promises), or will we need to add something that helps men “settle it”? You will never be able to do without the invitation system until you are thoroughly convinced of the power of God’s Word.
