Q. 109. What are the sins forbidden in the second commandment?
A. The sins forbidden in the second commandment are, all devising,[529] counselling,[530] commanding,[531] using,[532] and anywise approving, any religious worship not instituted by God himself;[533] tolerating a false religion; the making any representation of God, of all or of any of the three persons, either inwardly in our mind, or outwardly in any kind of image or likeness of any creature whatsoever;[534] all worshipping of it,[535] or God in it or by it;[536] the making of any representation of feigned deities,[537] and all worship of them, or service belonging to them,[538] all superstitious devices,[539] corrupting the worship of God,[540] adding to it, or taking from it,[541] whether invented and taken up of ourselves,[542] or received by tradition from others,[543] though under the title of antiquity,[544] custom,[545] devotion,[546] good intent, or any other pretence whatsoever;[547] simony;[548] sacrilege;[549] all neglect,[550] contempt,[551] hindering,[552] and opposing the worship and ordinances which God hath appointed.[553].
Charles H. Spurgeon said,
I do not believe that any man can preach the gospel who does not preach the law. The law is the needle, and you cannot draw the silken thread of the gospel through a man's heart unless you first send the needle of the law to make way for it. If men do not understand the law, they will not feel that they are sinners. And if they are not consciously sinners, they will never value the sin offering. There is no healing a man till the law has wounded him, no making him alive till the law has slain him.
D.L. Moody wrote,
The law stops every man's mouth. God will have a man humble himself down on his face before Him, with not a word to say for himself. Then God will speak to him, when he owns that he is a sinner, and gets rid of all his own righteousness.
C. Matthew McMahon wrote,
For we do not keep the Law to be saved. But rather, in keeping the Law we show ourselves to already have gained salvation through the cross of Christ. In light of the cross of Christ and the liberation from the (sting) of sin we receive from it, we are now free to keep the Law (Gal. 4:31).
