From the Word
For God so loved the world that he gave his only Son, that whoever believes in him should not perish but have eternal life.
John 3:16, RSV
With these words Jesus leads us directly into the Father’s heart, that we may see and know that it was the great and wonderful counsel of God, resolved from eternity, that we should receive help through his Son. All had to be fulfilled, that God’s truth might stand, even as he had promised in the Scriptures. It is thus apparent that God does not intend to cast us out, and to condemn us on account of our sins, but that he wills that we should attain to eternal grace and life for the sake of the Saviour and Mediator, if we fear his wrath on account of our sins, and keep in mind this eternal divine life.
The Holy Spirit teaches everywhere that we do not possess the Father except through a mediator, and he will not allow us to approach the Father without one. Let us thank the Father for ordering it as he has and placing between us one who is God and equal with God, and also man, on a level with man; for we are human and he is God. Where God and man oppose each other, man meets with instant destruction, for he cannot stand against God. God has intervened by placing as mediator one who is alike true God and true man. Through him we are to come to the Father; with the price we can pay nothing is accomplished.
If there were another way to heaven, Jesus would doubtless have made it known to us. Therefore let us cling to the words, firmly pilot our hearts along this way and keep within it. If I had the merits of all the saints, the sanctity and purity of all virgins, and the piety of St. Peter besides, still I would not give a fig for all I call my own. I must have another foundation on which to build, namely, the words: God has given his Son, that whosoever believeth in him, whom the Father sent out of love, shall be saved. Let us fearlessly plant ourselves on these words, which neither Satan, hell, nor death can overthrow. Come what will, let us say: Here is God’s Word; that is my rock and anchor; to that I cling and that abides; and where that abides, there I abide also. God cannot lie.
