What does Psalm 73:28 mean?

In this final verse of Psalm 73, Asaph counts his blessings. By contrast with the condition of the wicked who are far from God, Asaph knows it is good for him to be near God. He acknowledges that God is his fortress. He trusts in the Lord for safety, and he vows to proclaim all of God's works.

No doubt when Asaph left the temple, where he received God's answer to the issue of the prosperity of the wicked (Psalm 73:2–3, 15–18), he told others what he had learned. Believers today do not know everything, nor can we solve every problem that mankind faces, but we know the One who knows everything and can solve every problem (Isaiah 55:8–9). However, it is our privilege to tell others about Him and introduce them to Him (Matthew 28:19–20). Before the disciples declared God's wonderful works at Pentecost, they devoted themselves to prayer (Acts 1:14). Like Asaph and the disciples, we can prepare to carry out this task by first drawing near to God.
