"We must remember that to support a good cause is not enough; we must maintain it in a spirit equivalent to its dignity. Let no one touch the great interests of humanity who does not strive to sanctify himself for the work by cleansing his heart of all wrath and uncharitableness, who cannot hope that he is in a measure baptized into the spirit of universal love. Even sympathy with the injured and oppressed may do harm by being partial and exclusive and bitterly indignant." William Ellery Channing. 

I think this is such an important point! Sadly, I see and hear the gospel shared without this spirit of Universal love. Some share out of duty, some out of pride, some debate and make a contest of it; others share the precious truths with an exclusive spirit that separates and is permeated with a condescending air. And of course, some withdraw from sharing at all because they are repelled by the appearance or the life choices. 

The great teaching of Christianity is, that we must recognize and respect human nature in all its forms in the poorest, most ignorant, most fallen. We must look beneath "the flesh" to "the spirit".
