Blaise Pascal (1623–1662).
"The Christian religion then teaches men these two truths; that there is a God whom men can know, and that there is a corruption in their nature which renders them unworthy of Him. It is equally important to men to know both these points; and it is equally dangerous for man to know God without knowing his own wretchedness, and to know his own wretchedness without knowing the Redeemer who can free him from it. The knowledge of only one of these points gives rise either to the pride of philosophers, who have known God, and not their own wretchedness, or to the despair of atheists, who know their own wretchedness, but not the Redeemer.
And, as it is alike necessary to man to know these two points, so is it alike merciful of God to have made us know them. The Christian religion does this; it is in this that it consists.
Let us herein examine the order of the world, and see if all things do not tend to establish these two chief points of this religion: Jesus Christ is the end of all, and the centre to which all tends. Whoever knows Him knows the reason of everything.
Those who fall into error err only through failure to see one of these two things. We can then have an excellent knowledge of God without that of our own wretchedness, and of our own wretchedness without that of God. But we cannot know Jesus Christ without knowing at the same time both God and our own wretchedness."
We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself, and that wicked one toucheth him not. 19 [And] we know that we are of God, and the whole world lieth in wickedness. 20 And we know that the Son of God is come, and hath given us an understanding, that we may know him that is true, and we are in him that is true, [even] in his Son Jesus Christ. This is the true God, and eternal life. - 1 John 5:18-20
