Thus He showed at the same time that they had not yet been established in perfect faith, since they had not yet tasted communion with the Spirit. He offered as proof the cowardice that would soon be revealed in them.
He also appears to bring them no small benefit by foretelling what was about to happen to them. For they would be more firmly and strongly convinced that He is God by nature when they learned that He knows all things.
Behold, He says, the time is not far off. Rather, it is already coming, when, leaving "Me alone," you will go away "to your own." This can be expressed more clearly thus. When you yield to powerless cowardice, you will care only for your own life. Preferring your own safety to the love owed to the Teacher, you will withdraw to whatever places you find.
Is this, then, why you "now believe," if you have not yet removed from yourselves the shameful charge of cowardice, since you have not yet received boldness through the Spirit?
That the blessed disciples turned to flight, unable to endure the assault of the Jews when the traitor came leading an impious band of soldiers and officers' servants, admits not the slightest doubt. Then they left Christ "alone."
We say "alone" only in the sense that no one remained with Him from those who had usually followed Him and stayed with Him. For He was not alone as God from God, and in God by nature and indivisibly.
Christ also spoke this for us in a human manner. He teaches that, if time sometimes brings upon us temptation, persecution, or something similar, and calls us to glorious danger, I mean for the sake of piety, we must not lose hope of escape.
This remains true even if none of the like-minded brethren helps us, defending us as far as he can, and by his shared mind, as it were, dividing with us the danger threatening us.
For even if they turned to burdensome flight and showed in excessive measure an unconquerable cowardice, still we must be confident that God is not weakened because of this. He alone will be able to save the one devoted to Him.
We are not "alone," even if no one should be present, as I have just said, when we have almighty God as defender, helper, and protector. He shields us by His most merciful protection, according to the Psalmist's word: "O Lord, with the shield of Your good pleasure You have crowned us" (Ps 5:13).
We say this now not because we consider attachment to life a good thing when it is necessary for us to end bodily life with glory, struggling and contending against temptations for God's sake. Rather, we say it so that we may believe the opposite. Even if there are none who wish and strive to do this together with us, we must not despair. For we shall not be "alone" when God is present with us.
