Psalm 73 is a psalm from a believer who is doubting God. He confesses some things about God to be true, but his experience says something different. In the end, he's comforted by this truth, that distance from God is death, but nearness to God is safety and a life of praise. This nearness to God is through the Lord Jesus Christ alone. In this Psalm we get a glimpse of how Christ was ruthlessly tempted to doubt God and abandon his mission. And yet he persevered in order to draw us close to God.
