Psalm 15 Commentary
As a lecture, chapter 15 summarizes the essence of religion. It all boils down to obedience: being blameless; being righteous. That is the only qualification for entry into the presence of the LORD. Everyone can tell the truth. Each man has within himself the capacity to do what is right. Religion is this simple! The class can be dismissed. That is all there is to religion: obedience.
But this psalm is actually a prayer. David is speaking to himself on the need to stay blameless and righteous. It becomes personal. He should not exploit the poor. He should instead help them by not charging interest. He is ready to buy an apple at 5 dollars from the poor simply because he wants to help them.
He challenges himself with an obedience test. Will he keep the Law of the LORD even when it hurts?
Prayer is about presenting tons of requests in the presence of the LORD. But importantly, prayer is declaring the Law of the LORD loudly and communicating our responses. There is a law that forbids corruption and David’s response is to keep away from bribes. It is a verbal declaration of intention and commitment to obedience. And the LORD responds by planting the saint firmly against disobedience.
The saint can wake up in the morning and declare God’s law against lying. Then the saint can say, in Jesus’ name that by the power of the Holy Spirit, they shall not lie. Take stock of your day in the evening and you will be shocked at how well the LORD helps you keep His law. It’s a prayer that the LORD always answers.
