Every Sunday morning American Christians get up and enjoy one possible two doses of the Word of God. While this intake of God's Word is designed to be a compliment to a week filled with self study of God's Word, it is highly probable that for many this might be the only intake of God's Word.
To those that I have had the privilege to teach I enjoy likening the homily/lesson of pastor/teacher on Sunday morning to Gerber baby food - it's easily consumed, delivered by another, and there has been no effort on the part of the receiver in the preparation - in short they are consuming what has been "pre-chewed" by someone else! Imaging eating baby food all your life - the growth would not be impressive (convicting?)!
I like to say, Gerber is for baby, but the end game is Fillet Mignon - much better! The goal is to grow up and learn to "chew" your own food! Those that learn to "chew" God's Word for themselves (2 Tim 2:15) will find that the "pre-chewed" doses of God's Word that were once their only sustenance as "babes" in infancy becomes a delightful dessert or to complete the word picture the "icing on the cake" after a nice steak!
