Isaiah revealed that the Lord presented a wide open request to King Ahaz, “Moreover the LORD spoke again to Ahaz, saying, ‘Ask a sign for yourself from the LORD your God; ask it either in the depth or in the height above'” (Isaiah 7:10-11).
If the Lord let you have that request, what sign would you ask for, and to prove what?
When you have thought on that, go back to Isaiah 7, continue reading and see what King Ahaz said, and what the Lord gave the house of David as a sign, and ask yourself whether you would have asked for that sign.
The Lord does not think as we think, but what He does to show us the truth of all things far exceeds any sign that we could imagine. Praise the great God of heaven, for He knows what He is doing and He has proven all things sufficiently to us and for us.
