Heart-knowledge, we must always remember, is the one thing needful. It is something which schools and universities cannot confer. It is the gift of God. To find out the plague of our own hearts and hate sin–to become familiar with the throne of grace and the fountain of Christ’s blood–to sit daily at the feet of Jesus, and humbly learn of Him–this is the highest degree of knowledge to which mortal man can attain. Let any one thank God who knows anything of these things. One may be ignorant of Greek, Latin, Hebrew, and mathematics, but they shall be saved.
