- God is jealous because He alone is worthy of worship. - God is jealous because He knows that worshiping Him alone is best for us. (Psalm 115:4-8) God is a jealous God: 1) He wants your consistent worship. (v.1-3) The Lord wants our faith to be steady not sporadic. 2) He wants your exclusive worship. (v.4-20) The Lord is dishonored by spiritual infidelity. (Exodus 20:3) 3) He wants your holy worship. (v.21-31) The Lord desires worship that is not mingled with worldliness.
