1) A right heart is a NEW heart (Ezek. 36:26). It is not the heart with which a person is born—but another heart put in them by the Holy Spirit. It is a heart which has new tastes, new joys, new sorrows, new desires, new hopes, new fears, new likes, new dislikes. It has new views about the soul, sin, God, Christ, salvation, the Bible, prayer, heaven, hell, the world, and holiness. It is like a farm with a new and good tenant. “Old things are passed away. Behold all things are become new” (2 Cor. 5:17).
2) A right heart is a BROKEN and CONTRITE heart (Psalm 51:17). It is broken off from pride, self-conceit, and self-righteousness. Its former high thoughts of self are cracked, shattered, and shivered to atoms. It thinks itself guilty, unworthy, and corrupt. Its former stubbornness, heaviness, and insensibility have thawed, disappeared, and passed away. It no longer thinks lightly of offending God. It is tender, sensitive, and jealously fearful of running into sin (2 Kings 22:19). It is humble, lowly, and self-abased, and sees in itself no good thing.
3) A right heart is a heart which BELIEVES ON CHRIST ALONE for salvation, and in which Christ dwells by faith (Rom. 10:10; Eph. 3:17). It rests all its hopes of pardon and eternal life on Christ’s atonement, Christ’s mediation, and Christ’s intercession. It is sprinkled in Christ’s blood from an evil conscience (Heb. 10:22). It turns to Christ as the compass-needle turns to the north. It looks to Christ for daily peace, mercy, and grace—as the sun-flower looks to the sun. It feeds on Christ for its daily sustenance, as Israel fed on the manna in the wilderness. It sees in Christ a special fitness to supply all its needs and requirements. It leans on Him, hangs on Him, builds on Him, cleaves to Him, as its physician, guardian, husband, and friend.
4) 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.
