Saturdays with Calvin #33

Thou shalt have no other gods before me.

The purport of this commandment is, that the Lord will have himself alone to be exalted in his people, and claims the entire possession of them as his own. That it may be so, he orders us to abstain from ungodliness and superstition of every kind, by which the glory of his divinity is diminished or obscured; and, for the same reason, he requires us to worship and adore him with truly pious zeal. The simple terms used obviously amount to this. For seeing we cannot have God without embracing everything which belongs to him, the prohibition against having strange gods means, that nothing which belongs to him is to be transferred to any other. The duties which we owe to God are innumerable, but they seem to admit of being not improperly reduced to four heads: Adoration, with its accessory spiritual submission of conscience, Trust, Invocation, Thanksgiving. By Adoration, I mean the veneration and worship which we render to him when we do homage to his majesty; and hence I make part of it to consist in bringing our consciences into subjection to his Law. Trust, is secure resting in him under a recognition of his perfections, when, ascribing to him all power, wisdom, justice, goodness, and truth, we consider ourselves happy in having been brought into intercourse with him. Invocation, may be defined the retaking of ourselves to his promised aid as the only resource in every case of need. Thanksgiving, is the gratitude which ascribes to him the praise of all our blessings. As the Lord does not allow these to be derived from any other quarter, so he demands that they shall be referred entirely to himself. It is not enough to refrain from other gods. We must, at the same time, devote ourselves wholly to him, not acting like certain impious despisers, who regard it as the shortest method, to hold all religious observance in derision. But here precedence must be given to true religion, which will direct our minds to the living God. When duly imbued with the knowledge of him, the whole aim of our lives will be to revere, fear, and worship his majesty, to enjoy a share in his blessings, to have recourse to him in every difficulty, to acknowledge, laud, and celebrate the magnificence of his works, to make him, as it were, the sole aim of all our actions.
