Isaiah 28:16 (NLT) Therefore, this is what the Sovereign LORD says: “Look! I am placing a foundation stone in Jerusalem, a firm and tested stone. It is a precious cornerstone that is safe to build on. Whoever believes need never be shaken.
The hymn-writer wrote, "Change and decay in all around I see." Change and decay are enemies that most people fear... When we are young, change is a treat; but as we grow older, change becomes a threat. But when Jesus Christ is in control of your life, you need never fear change or decay... When you are part of eternity, the decay of the material only hastens the perfecting of the spiritual, if you walk by faith in Christ. -- Warren Wiersbe
