People think the Bible is too complicated for the average person to understand. People tend to be wrong. It's too complicated for the unsaved person, yes, it's foolishness to him. But for those who are in Christ, it's a magnificent journey of simplicity. Depth, richness, but simplicity. It's the fact that the natural man can't believe that life with Christ is so simple that cause the great complexity argument. Stop, take a breath, and believe that it's as simple as it appears.
