Isaiah 26:4 (NIV)
4 Trust in the Lord forever, for the Lord, the Lord himself, is the Rock eternal.

"Let us make ourselves easy by trusting in the Lord for ever; since God has promised peace to those that stay themselves upon him, let us not lose the benefit of that promise, but repose an entire confidence in him. Trust in him for ever, at all times, when you have nothing else to trust to; trust in him for that peace, that portion, which will be for ever.' Whatever we trust to the world for, it will be but for a moment: all we expect from it is confined within the limits of time. But what we trust in God for will last as long as we shall last. [Matthew Henry Commentary]

I remember watching a father play with his little boy, repeatedly throwing him in the air and catching him just before he hit the ground. The child is relaxed and having a great time saying, "Do it again! Do it again!"

I thought, If that was me, I 'd be stiff as a board .

"Can you explain why he's so relaxed, even when he's out of control?" I asked the father.

"It's very simple," he said. "We have a history together. We've played this game before, and I've never dropped him." [Rod Cooper, "Worship or Worry?" Preaching Today, Tape No. 108.]

God is our eternal Rock and is always there to catch us when we fall, so let us trust in The Lord Forever!
