There stood a man of Macedonia, and prayed him, saying, Come over into Macedonia, and help us. – Acts 16:9

Do you not know that the loudest eloquence is silence? To move the heart of the right-minded, ye need not the declamation of the orator. The sight of silent, dumb misery is the highest eloquence to a tender heart. It is true, I must confess it the nations of the earth do not vocally ask for your help; nay, worse than that, if you send them the help of the gospel, they will many of them reject it. Your missionaries have been slain, -the altars of false gods have been stained with their blood; but still I solemnly repeat it the nations of the earth are silently crying, “Come over and help us.” If I see a person in the street sick, faint, and dying, although he spoke not to me, though he asked me not to befriend him, I should think the weakness of his silence more potent than all the power of words. Ay, and if I saw him like a maniac, rejecting my help and pushing me from him, if I was convinced that he was really a maniac, for that very reason that he needed my help, I would thrust my alms upon him, I would willingly give him my help and assistance, and so must you do…It is ours to thrust our kindness upon unwilling men, because we believe that their unwillingness arises from the madness of their disease. Let us take the poor man that has fallen among thieves. Let us pour in the oil and the wine, and if he doth not receive it gratefully, because he is faint, if he putteth his hand upon the wound, and rends away the liniment, and unbinds the plaster, nevertheless. let us bind him up again, and set him upon our own beast, and carry him to the inn. Let us pay for the lodging even though as yet he cannot speak to thank us; and the day shall come, when the wound is healed, and the burning fever is removed, when his brain is cool, and his reason restored, that he shall fall at our feet and kiss the hand that once he spurned. Unborn generations shall bless the men that sent the gospel, which at first their fathers did reject.~ C.H. Spurgeon
