Thus you can easily understand what and how much this commandment requires, namely, that man's entire heart and all his confidence be placed in God alone, and in no one else. For to have God, you can easily perceive, is not to lay hold of Him with our hands or to put Him in a bag [as money], or to lock Him in a chest [as silver vessels]. But to apprehend Him means when the heart lays hold of Him and clings to Him. But to cling to Him with the heart is nothing else than to trust in Him entirely. For this reason He wishes to turn us away from everything else that exists outside of Him, and to draw us to Himself, namely, because He is the only eternal good. As though He would say: Whatever you have heretofore sought of the saints, or for whatever [things] you have trusted in Mammon or anything else, expect it all of Me, and regard Me as the one who will help you and pour out upon you richly all good things. Lo, here you have the meaning of the true honor and worship of God, which pleases God, and which He commands under penalty of eternal wrath, namely, that the heart know no other comfort or confidence than in Him, and do not suffer itself to be torn from Him, but, for Him, risk and disregard everything upon earth. On the other hand, you can easily see and judge how the world practices only false worship and idolatry. For no people has ever been so reprobate as not to institute and observe some divine worship; every one has set up as his special god whatever he looked to for blessings, help, and comfort. Thus, for example, the heathen who put their trust in power and dominion elevated Jupiter as the supreme god; the others, who were bent upon riches, happiness, or pleasure, and a life of ease, Hercules, Mercury, Venus or others; women with child, Diana or Lucina, and so on; thus every one made that his god to which his heart was inclined, so that even in the mind of the heathen to have a god means to trust and believe. But their error is this that their trust is false and wrong for it is not placed in the only God, besides whom there is truly no God in heaven or upon earth. Therefore the heathen really make their self-invented notions and dreams of God an idol, and put their trust in that which is altogether nothing. Thus it is with all idolatry; for it consists not merely in erecting an image and worshiping it, but rather in the heart, which stands gaping at something else, and seeks help and consolation from creatures saints, or devils, and neither cares for God, nor looks to Him for so much good as to believe that He is willing to help, neither believes that whatever good it experiences comes from God.
