Founded on Christ, the rock
When your soul is overcome by some temptation, it is not the temptation that turns you into chaff. No, you were chaff already, that is to say fickle and faithless; the temptation simply discloses the stuff you are made of… “Do you think I had any other purpose in making you,” said the Lord to Job, than to reveal your virtue?” (Jb 40:3 LXX) In another text he declares: “I humbled you and made you feel the pangs of hunger in order to find out what was in your heart” (Dt 8:3-5).
In the same way, a storm will not allow a house to stand firm if it is built upon sand. If you wish to build a house, you must build it upon rock. Then any storms that arise will not demolish your handiwork; whereas the house built upon sand will totter, proving thereby that it is not well founded. So while all is yet quiet, before the storm gathers, before the squalls begin to bluster or the waves to swell, let us concentrate all our efforts on the foundations of our building and construct our house with the many strong, interlocking bricks of God's commandments. Then when cruel persecution is unleashed like some fearful tornado against Christians, we shall be able to show that our house is built upon Christ Jesus our rock (1Cor 3:11).
