“We find in verse 14 a restatement of the Regulative Principle, this time applied to the works of God. In Proverbs, Solomon wrote, ‘do not add to His words, lest He rebuke you, and you be found a liar’ (Prov. 30:6). Here the same author writes, ‘I know that whatever God does, it shall be forever. Nothing can be added to it, and nothing taken from it.’

The common theme in these statements of Scripture, whether applied to worship (Deut. 12:32), or the sufficiency of God’s word (Prov. 30:6; Rev.20:18-19), or the sufficiency of His works (Eccl.3: 14), is the sufficiency of what God has provided, compared to the instability and untrustworthiness of the words and works of men. Matthew Henry writes ‘As the word of God, so the works of God are every one of them perfect in its kind, and it is presumption for us either to add to them or diminish from them, Deut. 4:2. It is therefore as much our interest, as our duty, to bring our wills to the will of God.’

The reason that God establishes His Word and works so that man cannot alter them by his inventions is also stated by Solomon: ‘God does it, that men should fear Him.’ It is nothing but the lack of godly fear that causes foolish creatures to take upon themselves to improve what God has established according to His unalterable will. All of the presumptuous additions introduced into God’s holy worship throughout Scripture were the expressions of men who did not properly fear the Lord. But God will require an account for each one.” (Comin, 204-205)
