Christ will be master of the heart, and sin must be mortified. If your life is unholy, then your heart is unchanged, and you are an unsaved person. The Savior will sanctify His people, renew them, give them a hatred of sin, and a love of holiness. The grace that does not make a man better than others is a worthless counterfeit. Christ saves His people, not IN their sins, but FROM their sins. Without holiness, no man shall see the Lord.
