- The unbeliever is restrained:
So how do we explain how it is that fallen man is able to do such deeds in the first place? The difficulty is brought out in the following Scriptures:
Matthew 7:18 A good tree cannot produce bad fruit, nor can a bad tree produce good fruit.
Matthew 12:34 You brood of vipers, how can you, being evil, speak what is good? For the mouth speaks out of that which fills the heart. The good man brings out of his good treasure what is good; and the evil man brings out of his evil treasure that which is evil.
In these verses the Lord is clearly using the terms good tree and good man to refer to those who are truly good (i.e., those born again with new natures), not to those who are simply “good” in the broader sense. His point is that good fruit cannot spring from a fallen nature. So how can the natural man produce fruit that can be described as “good” in any true sense at all?
Isn’t the implication of Scripture that when the natural man does things that are “good,” he is not acting out of his own fallen nature, but rather God is sovereignly overriding his nature and producing the good deed in him in spite of his evil nature. God’s restraint is a logical inference and one that is at least hinted at in several passages:
Genesis 20:6 I [God] also kept you [Abimelech] from sinning against Me…
Ezra 7:27 Blessed be the Lord…who has put such a [good] thing as this in the the king’s heart…
Psalm 16:2 My goodness is nothing apart from You.
The tragedy is that natural man does not recognize this sovereign, silent work of God in his life. This is a big part of why he has such a hard time realizing that his “good deeds” are as worthless as filthy rags in God’s sight. He does not think of his “goodness” as springing from God, as David did, but rather imagines it to spring from his own nature.
