And how shall they preach, except they be sent? – Romans 10:14

I wish that it were your habit to be always looking out for souls. Up then, you Christian men, and seek as God shall help you, by every means in your power, to make known Christ to the dying all around you! But you will not do it unless you are sent, driven, impelled, forced—you will not win souls for Christ until the Gospel is like a fire in your bones, and you feel that woe is unto you if you do not preach it.

Well now, before you go to try to do that, there is one thing more. You cannot do it effectively unless you are sent—and to be sent means to have power given you with which to do the work. Can that power be had? If you feel impelled to cry to God to give you the power to preach, the spiritual power, the power of the Holy Ghost, if you are propelled to teach in the Sunday school—and it is not worth doing unless you feel that you are impelled to it, and sent to it—then pray for the power to win the souls of those dear children for Christ. If you feel called upon to write a letter to a friend tomorrow about his soul or her soul, do it because you feel called upon to do it—but pray to God to show you how to do it. Pray to Him to put the power into the words that you utter, that you may say the right words, and put even the right tone into those words.

But the power being obtained, you must go forth and tell out the message that your Lord has given you. ~ C.H. Spurgeon
