The following commentary on Psalm 63:3, by The Expositor’s Bible Commentary, speaks of the rewards of seeking God fervently. The commentary on the entire Psalm is pasted in for those who might want to read it. As encouragement to do so, check out the one sentence with which MacArthur’s commentary described 63:3: better than life. God’s covenant love is more valuable to David than life itself (cf. Php_1:21; Act_20:24). Those verses: Philippians 1:21 For to me to live is Christ, and to die is gain. Acts 20:24 But I do not account my life of any value nor as precious to myself, if only I may finish my course and the ministry that I received from the Lord Jesus, to testify to the gospel of the grace of God. The words from Expositor’s commentary are a wonderful read that fill out the understanding regarding those two verses.
