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.
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.
It will not be we who reach Alpha Centauri, and the other nearby stars. It will be a species very like us - but with more of our strengths and fewer of our weaknesses.
Charity is having patience with someone who has let us down. It is resisting the impulse to become offended easily. It is accepting weaknesses and shortcomings. It is accepting people as they truly are. It is looking beyond physical appearances to attributes that will not dim through time. It is resisting the impulse to categorize others.
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.
