As for me, I will see Your face in righteousness; I shall be satisfied when I awake in Your likeness.
Listen to the "Verse by Verse" episode covering this scripture.
David contrasted his eternal hope with the focus of most people on temporary physical success in this world (verse 14). Instead of wealth and a full belly, David’s desire was to one day see God face to face, to awake in the very glorified likeness of God.
The apostle John also described this hope in 1 John 3:2: “We know that when He is revealed, we shall be like Him, for we shall see Him as He is.”
Such a hope should provoke a response in us: “And everyone who has this hope in Him purifies himself, just as He is pure” (verse 3).
