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.
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.
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.
