And the King shall answer and say unto them, Verily I say unto you, Inasmuch as ye have done it unto one of the least of these My brethren, ye have done it unto Me. – Matthew 25:40

There is a way of blessing God which, I trust, we shall all endeavour to practise; and that is by the doing good to His children. When they are sick, visit them. When they are downcast, comfort them. When they are poor, relieve them. When they are hard pressed by outward adversaries, stand at their side, and help them. You cannot bless the Head, but you can bless the feet; and when you have refreshed the feet, you have refreshed the Head. He will say, “Inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto Me.” If they be naked, and you clothe them; if they be sick, and you visit them; if they be hungry, and you feed them; you do in this respect bless God. David not only said, “Thou art my Lord: my goodness extendeth not to Thee;” but added, “but to the saints that are in the earth, and to the excellent in whom is all my delight.” You can be good to them, and in that respect, you may be blessing God. He has done so much for us, that we would fain do something for Him; and when we have reached the limit of our possibilities, we long to do more. We wish that we had more money to give, more talent to use, more time that we could devote to His cause; we wish that we had more heart and more brain; sometimes we wish that we had more tongue, and we sing, –

“Oh, for a thousand tongues to sing
My great Redeemer’s praise!”

This word “blessed” is an attempt to break the narrow circle of our capacity. It is an earnest endeavour of a burning heart to lay at God’s feet crowns of glory which it cannot find: “Blessed be the God and Father of our Lord Jesus Christ.” ~ C.H. Spurgeon
