Hebrews 2:1

Hebrews 2:1. Therefore we ought to give the more earnest heed to the things which we have heard, lest at any time we should let them slip.

We have heard them; do not let us forget them. Let them not be like the driftwood which goes floating down the stream. Let us make a desperate effort to retain them in our memories; and, above all, to ponder them in our hearts.
