“Therefore everyone who hears these words of Mine, and acts upon them, may be compared to a wise man, who built his house upon the rock. 25 “And the rain descended, and the floods came, and the winds blew, and burst against that house; and yet it did not fall, for it had been founded upon the rock. 26 “And everyone who hears these words of Mine, and does not act upon them, will be like a foolish man, who built his house upon the sand. 27 “And the rain descended, and the floods came, and the winds blew, and burst against that house; and it fell, and great was its fall.”
Here is a picture of two men, a wise man and a foolish man. The wise man had a true and good foundation. The foolish man had a foundation made of sand—it would not last.
In this illustration, the wise man is a Christian. His foundation is Christ. The foolish man is a non-Christian. His foundation is his own works and his own philosophy of life. But his foundation is not true and so it is unstable—as sand.
The rain and the floods and the wind represent the tests of our faith and what our life if built on. Notice that both the Christian and the non-Christian are tested.
The rain may represent things like illness, loss or disappointment. Floods may represent the world, or worldliness—“the lust of the flesh, the lust of the eyes, and the pride of life.” And the wind may represent Satanic attacks, such as to hurl doubts and evil thoughts at us.
Now for the non-Christian, the main disaster for him will come at the judgment, when it is discovered that there is no foundation, that Christ is not his Lord. The Christian does have a lasting foundation, which is Jesus Christ. But the trials of life will nevertheless test his faith to see how he has built upon that foundation (look at 1Corinthisna 3:12-15). And our rewards at the end of our life will depend on it.
One of the most important things for a Christian to do is to see to it that he has a good devotional life, and also that it doesn’t become mechanical. We must remember in our quiet times with the Lord, to stop and meditate on what we read from the bible, and listen to what God is telling us. Then determine to obey Him and to be always asking for His help and guidance along the way. He is our anchor and firm foundation.
