THEN I am to speak of the renewing nature and the new heart: "A new heart also will I give you, and a new spirit will I put within you; and I will take away the stony heart out of the flesh, and I will give you a heart of flesh," a new nature "And He that sat upon the throne said, Behold, I make all things new"--a new nature, a new heart, a tender conscience, the fear of God in the heart, the soul fitted and made meet for the inheritance of the saints in light. How can a natural man, an unregenerate man, one who loves the world, himself, sin, the flesh, and the devil, that delights in drunkenness and everything that is sinful, how could such a one delight in that holy, happy home, prepared for those who love and fear God? How could men who delight in the filthy conversation of the wicked, who frequent the public-house and get intoxicated, how could they make songs of praise to Jehovah, and ascribe to Him all he glory of their redemption? We might just as well call a lion a lamb, because the natural man is at enmity with God; "he is not subject to the law of God, neither indeed could be." He may be called a saint of God, but he never delights himself in holiness or heavenly praise. Just as the mole carried by an eagle to the top of a rock, he would be out of his element; just like a fish out of water on the dry land; so you see by this the necessity for this renewing. The Lord has made a beautiful promise: "A new heart will I give you, and a new spirit will I put within you." The necessity we see for this, because the old heart is "deceitful above all things, and desperately wicked." The Word of God tells us plainly that the thoughts and imaginations of the heart are only evil, and that continually. There must be a new heart and a new spirit. Every true-born child of God is taught to know that his union with the first Adam is death, but he that is united to the last Adam has a glorious resurrection; he hath a renewed nature, a divine nature. Every such soul will cry with the Psalmist, "Create in me a clean heart, and renew a right spirit within me."
