"Mindful of our human frailtyIs the God in whom we trust;He whose years are everlasting.He remembers we are dust."
"[T]he great Physician of souls knew how frail and how carnally minded [the disciples] were. He knew and understood all. Yet, he does not rebuke them; but in tender love he says, 'I have yet many things to say to you, but you cannot bear them now.'"
(From William Hendriksen's commentary on The Gospel of John. 16:12)
