2 Chronicles 26One of the lessons Uzziah learned (the hard way) was that faithfulness to the LORD does not mean doing all that you can do. It means following the LORD within the limits of one’s own gifting and sphere of influence. Uzziah should never have presumed to take on the role of priest. The coming Messiah would have both kingly and priestly functions, but not a single king or priest. Since Uzziah grew strong, he dared give people the impression that he might be the chosen Messiah. The priests were right to withstand him, but it took a lot of courage to openly rebuke a strong king.
LORD, use us within the spheres of influence that you have ordained for us. Give us wisdom to know where we are called, and where we should not venture.

Just a question Jeff, Uzziah was punished by the Lord for trying to do priestly functions, but do you think David did priestly functions as king? Didn’t David offer sacrifices? … We see that Saul also got in much trouble for trying to do what Samuel was to do, but it looks like David was able to do so in several instances. I would like your thoughts on that.
