"He Who is Zion's God is Zion's King, head over all things to the church; and this is her joy and comfort in every age, that her God and her King reigns, and will reign forevermore..." (John Gill) Zion's God is Zion's King. Regardless of feelings, David was resolved to extol his God. He knew Him to be the great God and a great King. The greatness of his God and King compelled David to elevate Him high in his praises, thoughts, speech, and conversation. Do you have a revelation of God's greatness?
