Know ye not that your body is the temple of the Holy Ghost [which is] in you, which ye have of God, and ye are not your own? – 1 Corinthians 6:19

The man who had a talent, and went and dug in the earth and hid it, had not he a right to do so? Yes, of course, if it was his own talent, and his own napkin. If any of you have money and do not put it out to interest, if it is all your own, nobody complains. But this talent belonged to the man’s master, it was only entrusted to him as a steward, and he ought not to have let it rust in the ground. So I have no right to let my faculties run to waste since they do not belong to me. If I am a Christian I have no right to be idle. I saw the other day men using picks in the road in laying down new gas-pipes; they had been resting, and just as I passed the clock struck one, and the foreman gave a signal. I think he said, “Blow up;” and straightway each man took his pick or his shovel, and they were all at it in earnest. Close to them stood a fellow with a pipe in his mouth, who did not join in the work, but stood in a free-and-easy posture. It did not make any difference to him whether it was one o’clock or six. Why not? Because he was his own: the other men were the master’s for the time being. He as an independent gentlemen might do as he liked, but those who were not their own fell to labor…A man who is his own may say, “I shall go whither I will, and do what I will;” but if I am not my own but belong to God who has bought me, then I must submit to His government; His will must be my will, and His directions must be my law. I desire to enter a certain garden, and I ask the gardener at the gate if I may come in. “You should be very welcome, sir, indeed,” says he, “if it were mine, but my master has told me not to admit strangers here, and therefore I must refuse you.” Sometimes the devil would come into the garden of our souls. We tell him that our flesh might consent, but the garden is not ours, and we cannot give him space. Worldly ambition, covetousness, and so forth, might claim to walk through our soul, but we say, “No, it is not our own; we cannot, therefore, do what our old will would do, but we desire to be obedient to the will of our Father who is in heaven.” Thy will be done, my God, in me, for so should it be done where all is Thine own by purchase. ~ C.H. Spurgeon
