Our good works spring from union with Christ. The more a man knows and feels himself to be one with Jesus, the more holy will he be. Why is a Christian's character like Christ's character? Only for this reason, that he is joined and united to the Lord Jesus. Why does the branch bring forth grapes? Simply because it has been engrafted into the vine, and therefore it partakes of the nature of the item. So, Christian, the only way whereby thou canst bring forth fruit to God is by being grafted into Christ and united with him.
