I see in another thread a lot of people saying that the best way to witness for Christ is by example, and I agree - to a point. The thing is, a lot of non-Christians do a lot of Christian-like-activities. Mormons, Scientologists, even athiests take care of the poor, feed the hungry, raise money for the sick. If we don't take the time to TELL people that the real difference is Christ. . . will they KNOW that the love you show is His love? How do you make sure that people know it is Christ and not humanistic?
