We are called to be worshippers of God. How are we to present ourselves in worship? From Psalm 15, Dr. John teaches on the qualities of heart, voice and action that God expects to see within those who come into His presence. Prayers of King David: Part of the appeal of the Psalms is that they speak to our current life situations with clarity and hope. In this five-message series, Dr. John points to the prayers of David from Psalms 13-17. Whether we are enduring difficult times, feel surrounded by ungodliness, are falsely accused or struggle to worship well, these Psalms are our prayers.
