Isaiah 25:7-8 ends with powerful words that Says; The LORD has Spoken! The word of our Lord will stand forever. If so, we are saved. If not, we are doomed. This is exactly where all true Christian preaching and ministry begins. We begin with absolute confidence in God’s promises precisely because we have absolute confidence in God’s Word. Our confidence is full because we have heard God speak, and we receive and trust his Word in all of its dimensions. We live by the Holy Scriptures because we know that they are the written Word of God. We trust in Christ, the incarnate Word, who, from the beginning, was with God and is God.
The Christian ministry is deadly serious business. The preacher stands to preach — what will he say? People who dwell in deep darkness desperately need a great light. Souls soon to face the eternal judgment of God desperately need to hear the blast of a trumpet. Sinners utterly without hope desperately hold onto a hope for hope. What will the preacher offer?
Flesh like grass, soon to wither and die, awaits a word. Fading flowers call out for rescue and an unfading hope. What is your message?
THE LORD HAS SPOKEN!
This great text points us to the great comprehensive story of redemption that is our assignment as preachers of the Word and ministers of the Gospel. We know the only message that brings the promise of true comfort. We know that in the atonement accomplished by Jesus Christ, we find our only sure hope for the pardon of our iniquities. In the Gospel of Christ, we declare that our warfare is ended.
Every single one of you is to be, in your own ministry, a voice that cries in the wilderness, “Prepare ye the way of the Lord.” In the majestic glory of a faithful Gospel ministry, mountains are laid low, and valleys are raised up, even as rough places are made plain.
Our great prayer for each of you and for all of you together is that the glory of God will be revealed in your ministry and in your lives so long as you may live — in the churches you will serve, the sermons you will preach, the lessons you will teach, the lives you will influence, the mission fields you will reach, and the sinners who will come to know Christ as Savior and Lord through your witness.
May you pour out your lives in service to the Gospel of Jesus Christ, the ministry of the Word, and the Church as the bride of Christ. Ground your ministry in the great story of God’s redemption of sinners through the blood of our Lord Jesus Christ. Declare comfort to the people of God, and feed them faithfully by preaching and teaching God’s Word.
On what authority do we know these things? Where do we find grounding for this knowledge? Isaiah settles these questions for all eternity with a singular sentence, and in this single sentence, we find all we need to ground our hopes for this life and for the life to come;
THE LORD HAS SPOKEN!
