Verse 17.— And the world passeth away.
Here we are informed that the world and all the lust thereof is transient; nothing permanent or abiding about it. Certainly a poor foundation upon which to build.
But he that doeth the will of God.
Here quite a different foundation is presented. Doing God's will insures something abiding; something enduring; no danger of being swept away; the only foundation that is essentially permanent.
