Much of David’s life saw him in tricky situations – some of them of his own making, some down to the sin of others. This Psalm seems to be set against such a backdrop – he starts by asking God for refuge. However, in this Psalm, he chooses not dwell on the things that are going wrong and coming against him, but rather on the goodness and faithfulness of God.
I had some interesting discussions with some young people over the summertime, who couldn’t get their heads around why God couldn’t just change the rules and let us off. We were talking about how, in our fallen state, we can’t come near to God in his holiness and perfection. Water and oil can’t mix. Light destroys dark.
