I have read quite a few devotionals from Oswald chambers to others
My favourite is come ye apart
BEGIN AT HOME He first findeth his own brother Simon ... and he brought him to Jesus. John 1:41-42 NOBODY told Andrew to go after his brother. It was the impulse of his own heart that sent him so quickly away on his errand of love, after he had found Jesus himself. The lesson lies on the surface. "Even a dog,” says the writer Alexander Maclaren, "that has had its leg mended will bring other limping dogs to the man that was kind to it.” One who has been cured of some disease will bring all his afflicted friends to the physician who cured him. You have had your soul saved. All about you are those whose souls are lost, as yours was a little while ago. How many have you brought to Jesus? Do you think you can hold
up clean hands, free from the blood of souls, unless you try earnestly to bring others to Jesus? Notice that it was his own brother that Andrew brought. The words indicate that the other man, John, brought his brother too ”’ only Andrew was quicker. Home, then, is the place where we ought to begin. Yet, strange to say, it is the last place many of us speak about Jesus. The old proverb has it, "The shoemaker’s wife is always the worst shod.” Often it is the preacher’s or the teacher’s own home that gets the least benefit and blessing from his messages of love, or from his Christian life and influence. Surely the dearest in the world to you are home’s precious ones. Go first to them, therefore, if any of them are unsaved, and try to bring them to your Saviour, that they may find what you have found
Of course, you will not stop with home. Let the circle widen until your influence reaches as widely as possible; but do not overlook home and those nearest and dearest to you while you stretch out your hands toward mission fields in foreign lands, or even reach over the fence to save a neighbour. That is a mistake some people make
