1 Peter 1:21

21Who believe The manifestation of Christ refers not to all indiscriminately, but belongs to those only on whom he by the Gospel shines. But we must notice the words, Who by him believe in God: here is shortly expressed what faith is. For, since God is incomprehensible, faith could never reach to him, except it had an immediate regard to Christ. Nay, there are two reasons why faith could not be in God, except Christ intervened as a Mediator: first, the greatness of the divine glory must be taken to the account, and at the same time the littleness of our capacity. Our acuteness is doubtless very far from being capable of ascending so high as to comprehend God. Hence all knowledge of God without Christ is a vast abyss which immediately swallows up all our thoughts. A clear proof of this we have, not only in the Turks and the Jews, who in the place of God worship their own dreams, but also in the Papists. Common is that axiom of the schools, that God is the object of faith. Thus of hidden majesty, Christ being overlooked, they largely and refinedly speculate; but with what success? They entangle themselves in astounding dotages, so that there is no end to their wanderings. For faith, as they think, is nothing else but an imaginative speculation. Let us, therefore, remember, that Christ is not in vain called the image of the invisible God, (Colossians 1:15;) but this name is given to him for this reason, because God cannot be known except in him.

The second reason is, that as faith unites us to God, we shun and dread every access to him, except a Mediator comes who can deliver us from fear. For sin, which reigns in us, renders us hateful to God and him to us. Hence, as soon as mention is made of God, we must necessarily be filled with dread; and if we approach him, his justice is like fire, which will wholly consume us.

It is hence evident that we cannot believe in God except through Christ, in whom God in a manner makes himself little, that he might accommodate himself to our comprehension; and it is Christ alone who can tranquillize consciences, so that we may dare to come in confidence to God.

That raised him up from the dead He adds, that Christ had been raised up from the dead, in order that their faith and hope, by which they were supported, might have a firm foundation. And hereby again is confuted the gloss respecting universal and indiscriminate faith in God; for had there been no resurrection of Christ, still God would remain in heaven. But Peter says that he would not have been believed in, except Christ had risen. It is then evident, that faith is something else than to behold the naked majesty of God. And rightly does Peter speak in this manner; for it belongs to faith to penetrate into heaven, that it may find the Father there: how could it do so, except it had Christ as a leader?

“By him,” says Paul, “we have confidence of access.”
(Ephesians 3:12.)

It is said also, in Hebrews 4:16, that relying on our high priest, we can come with confidence to the throne of grace. Hope is the anchor of the soul, which enter into the inner part of the sanctuary; but not without Christ going before. (Hebrews 6:19.) Faith is our victory against the world, (1 John 5:4) and what is it that makes it victorious, except that Christ, the Lord of heaven and earth, has us under his guardianship and protection?

As, then, our salvation depends on the resurrection of Christ and his supreme power, faith and hope find here what can support them. For, except he had by rising again triumphed over death, and held now the highest sovereignty, to protect us by his power, what would become of us, exposed to so great a power as that of our enemies, and to such violent attacks? Let us, therefore, learn to what mark we ought to direct our aim, so that we may really believe in God.
