A right heart is a PURIFIED heart (Acts 15:9; Matt. 5:8). It loves holiness, and hates sin. It strives daily to cleanse itself from all filthiness of flesh and spirit (2 Cor. 7:1). It abhors that which is evil, and cleaves to that which is good. It delights in the law of God, and has that law engraved on it, that it may not forget it (Psalm 119:11). It longs to keep the law more perfectly, and takes pleasure in those who love the law. It loves God and people. Its affections are set on things above. It never feels so light and happy as when it is most holy; and it looks forward to heaven with joy, as the place where perfect holiness will at length be attained.
