Are you ready for anything? If someone asked you to teach them something about God could you do it right there and then? If the answer is no, you have some work to do. We are to be ready, at a moments notice to teach something about God. Further what we teach ought to be truth, not simply our impressions of truth. This will mean a life drenched in God where we are connecting with God. If we do not we could fall pray to all sorts of teaching.
We are warned the day will come when people will gather around them people who tell them what they want to hear. I cannot help but think of Michael Jackson. Since his death we have heard from several people who were advising Mr. Jackson in his life and affairs. Many of them did so at great personal financial gain. It is easy to see how some of these people did not do what was in the best interest of Jackson, rather they did what he asked them to do. The results were tragic.
It is important we a rooted and grounded in truth, and we surround ourselves with people who will hold us accountable, not only tell us what we want to hear.
