I've had a hymn stuck in my head for days: "My Hope Is Built on Nothing Less." It's got a catchy tune (if sung to Solid Rock, which I do) and refrain, which is handy since I'm recalling it from memory.
Sometimes a good hymn helps.
The text is a reference to the parable of the man who built his house on a rock, in Matthew 7. Hosea Ballou commented on verses 24 and 25 in his Notes on the Parables: "By house I understand the hope or confidence in which the mind rests. By rock, I understand Christ; which application is too evident to need proof. And what can compare with that wisdom which teaches us to put our trust in Christ, and build all our hopes of salvation on that rock of ages, that chief corner stone which foolish builders refuse?"
A foundation of rock sounds pretty good to me, and hardly too much to ask for.
