We are to consider in the ten commandments, the preface, the substance of the commandments themselves, and the several reasons annexed to some of them the more to enforce them.
The preface to the ten commandments is contained in these words, I am the Lord thy God, which have brought thee out of the land of Egypt, out of the house of bondage. Wherein God manifesteth his sovereignty, as being Jehovah, the eternal, immutable, and almighty God; having his being in and of himself, and giving being to all his words and works: and that he is a God in covenant, as with Israel of old, so with all his people; who, as he brought them out of their bondage in Egypt, so he delivereth us from our spiritual thraldom: and that therefore we are bound to take him for our God alone, and to keep all his commandments.
The sum of the four commandments containing our duty to God, is, to love the Lord our God with all our heart, and with all our soul, and with all our strength, and with all our mind.
The first commandment is, Thou shalt have no other gods before me.
The duties required in the first commandment are, the knowing and acknowledging of God to be the only true God, and our God; and to worship and glorify him accordingly, by thinking, meditating, remembering, highly esteeming, honoring, adoring, choosing, loving, desiring, fearing of him; believing him; trusting, hoping, delighting, rejoicing in him; being zealous for him; calling upon him; giving all praise and thanks, and yielding all obedience and submission to him with the whole man; being careful in all things to please him, and sorrowful when in anything he is offended; and walking humbly with him.
The sins forbidden in the first commandment are atheism, in denying, or not having a God; idolatry, in having or worshiping more gods than one, or any with, or instead of the true God; the not having and avouching him for God, and our God; the omission or neglect of any thing due to him, required in this commandment; ignorance, forgetfulness, misapprehensions, false opinions, unworthy and wicked thoughts of him; bold and curious searching into his secrets; all profaneness, hatred of God; self-love, self-seeking, and all other inordinate and immoderate setting of our mind, will, or affections upon other things, and taking them off from him in whole or in part; vain credulity, unbelief, heresy, misbelief, distrust, despair, incorrigibleness, and insensibleness under judgments; hardness of heart; pride; presumption; carnal security; tempting of God; using unlawful means, and trusting in lawful means; carnal delights and joys; corrupt, blind, and indiscreet zeal; lukewarmness, and deadness in the things of God; estranging ourselves, and apostatizing from God; praying, or giving any religious worship, to saints, angels, or any other creatures; all compacts and consulting with the devil, and hearkening to his suggestions; making men the lords of our faith and conscience; slighting and despising God and his commands; resisting and grieving of his Spirit, discontent and impatience at his dispensations, charging him foolishly for the evils he inflicts on us; and ascribing the praise of any good we either are, have, or can do, to fortune, idols, ourselves, or any other creature.
The second commandment is, Thou shalt not make unto thee any graven image, or any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth: thou shalt not bow down thyself to them, nor serve them: for I the Lord thy God am a jealous God, visiting the iniquity of the fathers upon the children, unto the third and fourth generation of them that hate me; and showing mercy unto thousands of them that love me, and keep my commandments.
The duties required in the second commandment are, the receiving, observing, and keeping pure and entire, all such religious worship and ordinances as God hath instituted in his Word; particularly prayer and thanksgiving in the name of Christ; the reading, preaching, and hearing of the Word; the administration and receiving of the sacraments; church government and discipline; the ministry and maintenance thereof; religious fasting; swearing by the name of God, and vowing unto him: as also the disapproving, detesting, opposing, all false worship; and, according to each one’s place and calling, removing it, and all monuments of idolatry.
The sins forbidden in the second commandment are, all devising, counselling, commanding, using, and anywise approving, any religious worship not instituted by God himself; 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; all worshiping of it, or God in it or by it; the making of any representation of feigned deities, and all worship of them, or service belonging to them; all superstitious devices, corrupting the worship of God, adding to it, or taking from it, whether invented and taken up of ourselves, or received by tradition from others, though under the title of antiquity, custom, devotion, good intent, or any other pretence whatsoever; simony; sacrilege; all neglect, contempt, hindering, and opposing the worship and ordinances which God hath appointed.
