Without Zeal, our Duties are not Acceptable to God

In this let us be like Christ, zealous for God’s truth and glory, which are the two orient pearls of the crown of heaven. Zeal is as needful for a Christian as salt for the sacrifice, or fire on the altar. Zeal without prudence is rashness; prudence without zeal is cowardliness. Without zeal, our duties are not acceptable to God. Zeal is like rosin to the bow-strings, without which the lute makes no music. “A Body of Divinity” pg. 201
