Psalm 26

David found a level place before the LORD. There he took his stand. But he wasn't a silent watchtower; he spoke about God. From this psalm David says that he speaks of God's justice, and his faithfulness to those who are faithful to him. David was prepared to address the crowds. It didn't matter if the crowd desired David's words of praise or not he was ready to speak about the God who is actively working in the lives of his people. The people were gathered to worship God, they should hear of his works. There were surely some who didn't want to hear David's words, just as there were people who who didn't want to hear Jesus speak.
It took me about 3 minutes to read this psalm.
