Psalm 42 was written by a Korahite, a temple singer, who in exile was kept from his duties among God’s people. He longs for the day when he can again participate in temple worship, perhaps even leading the procession to the holy place. He agonizes and questions his present suffering, but the great refrain of the psalm (vv. 5, 11) is to wait for God, to hope in him and give him thanks, for he is Savior.
It is noteworthy that the author does what he did best: he wrote a song and sang it. It wasn’t in the temple, but he used his talents to do what he could under the restrictions he was subjected to.
The psalm can have a good application to us who are used to serving the Lord in specific ways and with well-defined gifts. We may not be able to do that today, because of the social distancing. But we can still use the talents God gives us within our limitations. We may agonize and question, as the psalmist did, but he encourages us to wait for God and, in the meantime, do what is within our possibility.
