The final words of the psalm — 'he hath done this' — are a declaration of accomplished fact. In Hebrew this is a triumphant shout. Some scholars connect this to Jesus' cry 'It is finished' on the cross (John 19:30). The psalm that began in desolation ends in eternal declaration.
Memory phrase: God has done it — it is finished!
Talk about it: What did Jesus mean when He cried 'It is finished!' on the cross? What was 'done'?
Prayer: God, 'It is finished!' — Jesus said it from the cross, and this psalm shouted it 1,000 years before. Thank You for doing what only You could do.
