"It pleased God... to reveal His Son in me," wrote Paul (Gal. i. 15, 16); and again, "Christ liveth in me" (Gal. ii. 20); and again, "My little children, of whom I travail in birth again until Christ be formed in you" (Gal. iv. 19); as though Christ is to be spiritually formed in the heart of each believer by the operation of the Holy Spirit, as He was physically formed in the womb of Mary by the same Spirit (Luke i. 35); and again, "The mystery which hath been hid from ages and from generations, but now is made manifest to His saints,... which is Christ in you, the hope of glory" (Col. i. 26, 27); "That Christ may dwell in your hearts by faith" (Eph. iii. 17); "Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates" (2 Cor. xiii. 5)? "At that day," said Jesus, when making His great promise of the Comforter to His disciples, "At that day ye shall know that I am in My Father, and ye in Me, and I in you" (John xiv. 20); and again, in His great prayer, He said: "I have declared unto them Thy name, and will declare it: that the love wherewith Thou hast loved Me may be in them, and I in them." It is this ever-recurring revelation to penitent, believing hearts, by the agency of the ever-present Holy Spirit, that makes faith in Jesus Christ living and invincible. "I know He is Lord, for He saves my soul from sin, and He saves me now," is an argument that rationalism and unbelief cannot answer nor overthrow, and so long as there are men in the world who can say this, faith in the divinity of Jesus Christ is secure; and this experience and witness come by the Holy Ghost. "I worship Thee, O Holy Ghost, I love to worship Thee; My risen Lord for aye were lost But for Thy company." And so it is by the guidance and teaching of the Holy Spirit that all saving truth becomes vital to us. It is He that makes the Bible a living Book; it is He that convinces the world of judgment (John xvi. 8-11); it is He that makes men certain that there is a Heaven of surpassing and enduring glory and joy, and a Hell of endless sorrow and woe for those who sin away their day of grace and die in impenitence. Who have been the mightiest and most faithful preachers of the gloom and terror and pain of a perpetual Hell? those who have been the mightiest and most effective preachers of God's compassionate love.
