Surely it was better that these stones should be torn out, even amid agony, and built into the wall of the church, than that they should have lain ages more, undisturbed in the dark quarry.

They were saved from uselessness by being destroyed.
These are simple illustrations of the law which applies also in human life.

We must die to be useful--to be truly a blessing.

Our Lord put this truth in a little parable, when he said that the seed must fall into the earth and die that it may bear fruit.

Christ's own cross is the highest illustration of this.
