I just read these words from Charles Spurgeon, and they're driving me to think more deeply as I review my sermon for today. Spurgeon has a way of slicing into my soul . . . .
One thing more, and it is this. Let us, dear brethren, try to get saturated with the gospel. I always find that I can preach best when I can manage to lie a-soak in my text. I like to get a text, and find out its meaning and bearings, and so on; and then, after I have bathed in it, I delight to lie down in it, and let it soak into me. It softens me, or hardens me, or does whatever it ought to do to me, and then I can talk about it.
You need not be very particular about the words and phrases if the spirit of the text has filled you; thoughts will leap out, and find raiment for themselves. Become saturated with spices, and you will smell of them; a sweet perfume will distil from you, and spread itself in every direction; we call it unction. Do you not love to listen to a brother who abides in fellowship with the Lord Jesus? Even a few minutes with such a man is refreshing, for, like his Master, his paths drop fatness.
Dwell in the truth, and let the truth dwell in you. Be baptized into its spirit and influence, that you may impart thereof to others. If you do not believe the gospel, do not preach it, for you lack an essential qualification; but even if you do believe it, do not preach it until you have taken it up into yourself as the wick takes up the oil. So only can you be a burning and a shining light.
