I remember hearing of a dear old Christian who was troubled with a bad memory. He seemed to forget everything he wanted to remember. At last a happy thought struck him. Why not ask the Lord to remember for him? Accordingly, the next time he heard anything good which he desired to retain, he simply looked up and said, "Now Lord, keep that for me till I need it," and he continued this practice to the end.
"The time of need" evidently did not come to the dear old saint till he was lying on his deathbed; then the blessed truths which he had "banked" with the Lord were again returned to him, no doubt with interest, for the comfort and joy of his own soul. But not only so; they rolled out of his lips for the comfort, joy, and blessing of others also.
Often have I thought of the dear old man! What a wise thing to do! What a safe bank to put his spiritual treasures in! What a gracious God to commit them to! He knows best when we need them, and when to return them to us. When He does that, it is real food for the soul.
