Listen, my beloved brethren: Has God not chosen the poor of this world to be rich in faith and heirs of the kingdom which He promised to those who love Him? – James 2:5

Sympathy may often be the direct means of conversion…Go to the poor man and tell him of the bread of heaven, but first give him the bread of earth, for how shall he hear you with a starving body? Talk to him of the robe of Jesus’ righteousness, but you will do it all the better when you have provided a garment with which he may cover his nakedness. It seems an idle tale to a poor man if you talk to him of spiritual things and cruelly refuse him help as to temporals. Sympathy, thus expressed, may be a mighty instrument for good; and even without this, if you be too poor to be able to carry out the pecuniary part of benevolence, a kind word, a look, a sentence or two of sympathy in trouble, a little loving advice, or an exhortation to your neighbor to cast his burden on the Lord, may do much spiritual service. I do not know, but I think if all our Church-members were full of love, and would always deal kindly, there would be very few hearts that would long hold out, at least from hearing the Word. You ask a person to hear your preacher; but he knows that you are crotchety, short-tempered, illiberal, and he is not likely to think much of the Word which, as he thinks, has made you what you are; but if, on the other hand, he sees your compassionate spirit, he will first be attracted to you, then next to what you have to say, and then you may lead him as with a thread, and bring him to listen to the truth as it is in Jesus, and who can tell but thus, through the sympathy of your tender heart, you may be the means of bringing him to Christ. ~ C.H. Spurgeon
