The weak have no place here, in this life or any other life. Weakness leads to slavery. Weakness leads to all kinds of misery, physical and mental. Weakness is death.
Whenever the strength of a belief strongly steps into the foreground, we must infer a certain weakness of demonstrability and the improbability of that belief.
My weaknesses... I wish I could come up with something. I'd probably have the same pause if you asked me what my strengths are. Maybe they're the same thing.
God's word is:
'He who strives never perishes.'
I have implicit faith in that promise.
Though, therefore, from my weakness
I fail a thousand times, I shall not lose faith.
If your knowledge teaches you not to rise above human weakness and misery and lead your fellow man on the right path, you are indeed a man of little worth and will remain such till Judgment Day.
