And I will pray the Father, and He shall give you another Comforter, that He may abide with you for ever… – John 14:16

Our God would not have His children unhappy, and therefore, He Himself, in the third Person of the blessed Trinity, has undertaken the office of Comforter. Why does your face such mournful colours wear? God can comfort you. You that are under the burden of sin; it is true no man can help you into peace, but the Holy Ghost can. O God, to every seeker here who has failed to find rest, grant Thy Holy Spirit! Put Thy Spirit within him, and he will rest in Jesus. And you dear people of God, who are worried, remember that worry and the Holy Ghost are very contradictory one to another. “I will put My spirit within you” means that you shall become gentle, peaceful, resigned, and acquiescent in the divine will. Then you will have faith in God that all is well… David says- “God my exceeding joy”; and such He is to us. “Yea, mine own God is He”! Can you say, “My God, my God”? Do you want anything more? Can you conceive of anything beyond your God? Omnipotent to work all for ever! Infinite to give! Faithful to remember! He is all that is good. Light only: “in Him is no darkness at all.” I have all light, yea, all things, when I have my God. The Holy Spirit makes us apprehend this when He is put within us. Holy Comforter, abide with us, for then we enjoy the light of heaven. Then are we always peaceful and even joyful; for we walk in unclouded light. In Him our happiness sometimes rises into great waves of delight, as if it leaped up to the glory! Amen! ~ C.H. Spurgeon
