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.
I do not love thee less for what is done,
And cannot be undone. Thy very weakness
Hath brought thee nearer to me, and henceforth
My love will have a sense of pity in it,
Making it less a worship than before.
Nothing is here for tears, nothing to wail Or knock the breast, no weakness, no contempt, Dispraise, or blame,-nothing but well and fair, And what may quiet us in a death so noble.
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.
