In Psalm 27:4, David confesses the one thing he desires is to gaze upon the beauty of the LORD.
When we look at objects with our bodily eyes, we can’t see ourselves. Likewise, when our heart’s attention is gazed upon the perfect Lord, we can’t pay any attention to the imperfect self.
In The Pursuit of God, A.W. Tozer states believing (i.e., faith) is directing the heart’s attention to Jesus.
As in Hebrews 12:1-2, let us not look at our weights and sins, but let us run with endurance the race that is set before us by looking to Jesus, the founder and perfecter of our faith.
