Theophylact of Bulgaria
He adds something else that draws them to endure sorrows. What is it? The following: "Whom, having not seen, you love."
If, he says, you love Him by hearing alone, though you have not seen Him with bodily eyes, what love will you feel when you see Him, and see Him appearing in glory?
If His sufferings so attached you to Him, what attachment should His appearing in unbearable radiance produce in you, when the salvation of your souls will be given to you as a reward?
If you are to appear before Him and be counted worthy of such glory, then now show patience corresponding to it. Thus you will fully attain the goal set before you.
