Remembering is sometimes a command, and that means forgetting is sometimes a sin. This great Psalm teaches us how, what, and why we should remember. Speaking of memory, a few of you might remember that I preached this Psalm more than a decade ago when I was IBC’s candidate for Pastor of Student Ministries. For nearly three thousand years, Psalm 78 has stood as a reminder that one of our dearest tasks is to teach and train the next generation to know, trust, and obey the good Lord who shepherds us. That’s what Teen Week is all about.
