Whosoever shall deny me - Whosoever prefers his worldly interest to his duty to God, sets a greater value on earthly than on heavenly things, and prefers the friendship of men to the approbation of God.

Let it be remembered, that to be renounced by Christ is to have him neither for a Mediator nor Savior. To appear before the tribunal of God without having Christ for our Advocate, and, on the contrary, to have him there as our Judge, and a witness against us, - how can a man think of this and not die with horror!

On the Words of the Gospel, Matt. x. 16, "Behold, I Send You Forth as Sheep in the Midst of Wolves," Etc. Delivered on a Festival
