“Then the eyes of the blind will be opened and the ears of the deaf will be unstopped. Then the lame will leap like a deer, and the tongue of the mute will shout for joy. For the water will break forth in the wilderness and streams in the Arabah.” Isaiah 35:5-6 (NASB)
Grace makes a great difference in a man, when it enters into him. How vain, then, are the boasts and professions of some persons, who assert themselves to be the children of God, and yet live in sin. There is no perceivable difference in their conduct; they are just what they used to be before their pretended conversion; they are not changed in their acts, even in the least degree, and yet they do most positively affirm that they are the called and living children of God, although they are entirely unchanged. Let such know that their pretensions are lies, and that falsehood is the only groundwork that they have for their hopes; for, wherever the grace of God is, it makes men to differ. A graceless man is not like a gracious man: and a gracious man is not like a graceless one.
We are “new creatures in Christ Jesus.” When God looks upon us with the eye of love, in conversion and regeneration, He makes us as opposite from what we were before as light is from darkness, as even heaven itself is from hell. God changes man. He works in him a change so great, that no reformation can even so much as thoroughly imitate it; it is an entire change–a change of the will, of the being, of the desires, of the hates, of the dislikings, and of the likings. In every respect the man becomes new when divine grace enters into his heart.
