Today, all sorts of subjects are eagerly pursued; but the knowledge of God is neglected.
Yet to know God is man's chief end, and justifies his existence.
Even if a hundred lives were ours, this one aim would be sufficient for them all.
John Calvin, Commenting on Jeremiah 9:24:
Let him who boasts boast in this,
That he understands and knows me,
That I am the Lord who practices steadfast love,
Justice, and righteousness in the earth.
For in these things I delight, declares the Lord.
