Zeal is the passionate response of a willing heart to the goodness and mercy of an all wise, loving, Heavenly father. As a passion, it must be tempered by the Word of God and God the Holy Spirit. Zeal is expressed in Scripture as an attribute of a Holy God. We should seek to adorn His attributes. In our passion, we should provoke others to good works and following the Lord. This will be seen as zeal to some and normal to others. However it will greatly please our Heavenly Father.
