… Give love to them that need it most. The most unfortunate, those who have the most disagreeable temperaments need our love, our tenderness, our compassion. Those who try our patience need most love. We pass through the world only once; any good thing we can do, we should do most earnestly, untiringly, with the same spirit as is stated of Christ in His work. He will not fail nor be discouraged. The rough, stubborn, sullen dispositions are the ones who need help the most. How can they be helped? Only by that love practiced in dealing with them which Christ revealed to fallen man. Treat them, you may, as they deserve. What if Christ had treated us thus? He, the undeserving, was treated as we deserve. Still we are treated by Christ with grace and love as we did not deserve, but as He deserved. Treat some characters, as you think they richly deserve, and you will cut off from them the last thread of hope, spoil your influence and ruin the soul. Will it pay? No, I say no, a hundred times no. Bind these souls who need all the help it is possible for you to give them close to a loving, sympathizing, pitying heart, overflowing with Christlike love, and you will save a soul from death and hide a multitude of sins. Had we not better try the love process?
