Albert Barnes Commentary Psalms 107:21

"Oh that men would praise Jehovah for his lovingkindness, And for his wonderful works to the children of men!" — Psalms 107:21 (ASV)

Oh that men... - See the notes at (Psalms 107:8). Who can help joining in this wish, that those who have been restored from sickness, who have been raised up from the borders of the grave, would praise God for it! Who can help wishing that they had the feelings of Hezekiah when he was saved from the sickness which threatened his life—saved by the direct and manifest interposition of God—when he said (Isaiah 38:20), The Lord was ready to save me: therefore we will sing my songs to the stringed instruments, all the days of our life in the house of the Lord! Who can help wishing that people everywhere would see in such interpositions the proof of the benevolence of God, and would thank him that he has not forgotten guilty and suffering people!
