16:28-33 Here is a plain declaration of Christ's coming from the Father, and his return to him. The Redeemer, in his entrance, was God manifest in the flesh, and in his departure was received up into glory. By this saying the disciples improved in knowledge. Also in faith; Now are we sure. Alas! they knew not their own weakness. The Divine nature did not desert the human nature, but supported it, and put comfort and value into Christ's sufferings. And while we have God's favourable presence, we are happy, and ought to be easy, though all the world forsake us. Peace in Christ is the only true peace, in him alone believers have it. Through him we have peace with God, and so in him we have peace in our own minds. We ought to be encouraged, because Christ has overcome the world before us. But while we think we stand, let us take heed lest we fall. We know not how we should act if brought into temptation; let us watch and pray without ceasing, that we may not be left to ourselves.

33. These things I have spoken unto you—not the immediately preceding words, but this whole discourse, of which these were the very last words, and which He thus winds up.

that in me ye might have peace—in the sublime sense before explained. (See on [1868]Joh 14:27).

In the world ye shall have tribulation—specially arising from its deadly opposition to those who "are not of the world, but chosen out of the world." So that the "peace" promised was far from an unruffled one.

I have overcome the world—not only before you, but for you, that ye may be able to do the same (1Jo 5:4, 5).
