I agree heartily with Ron. It is impossible to give people meaningful lessons unless I fill up my mind and heart first. The principle method is reading. If we preach from the overflow, then we’ve got to overfill the mind with good, profitable reading materials. Lately, I’ve been reading the two books on Psalms written by the Truth-For-Today writer Eddie Cloer. I’m also reading the Jewish history volumes by Schurer and I’m still getting a great deal from Rex Turner Sr.’s book on Systematic Theology. Got to fill up the old tank if you want to go anywhere.
