It can never be asked too often--have you opened your Bible to study your lesson? It is certainly easier to search the internet for a lesson, or maybe purchase Bible material from a Bible store, and, yes, even to read this blog, but do you consistently, purposefully, prayerfully, and diligently study God's Word to see what God has to say about your lesson? Do you have all the facts correct? Have you added "what you believe to be true" or maybe you have left out something important because you "didn't remember it that way?" Check yourself with God's words (2 Timothy 3:16, 17). Don't be afraid or too self-assured to open up the Bible and read (1 Thessalonians 5:21) . We all make mistakes (Romans 3:23).
All other sources can be mistaken about Bible facts, but when we open up the Bible and read the lesson from the Bible with our own eyes and diligently study the facts, we can be assured that what we are teaching young, impressionable minds is Truth. How difficult it is to "unteach" something that we have, perhaps innocently, taught wrong. We need to always have book, chapter, and verse for what we teach, then we can confidently and with certainty teach the scriptures to precious ones. What a noble task it is to "search the scriptures daily to see whether those things" are so (Acts 17:11). May we all open up our Bibles and read.
