…and he went out, not knowing whither he went. – Hebrews 11:8

God bade Abraham journey, and he moved his camp at once. Into the unknown land he made his way; through fertile regions, or across a wilderness; among friends or through the midst of foes, he pursued his journey. He did not know where his way would take him, but he knew that the Lord had bidden him go…The Abrahams of to-day will not go out from their kindred; they will put up with anything sooner than risk their livelihoods. If they do go out, they must know where they are going, and how much is to be picked up in the new country. I am not pronouncing any judgement upon their conduct; I am merely pointing out the fact. Our Puritan forefathers reeked little of property or liberty when these stood in the way of conscience: they defied exile and danger sooner than give up a grain of truth; but their descendants prefer peace and worldly amusements, and pride themselves on “culture” rather than on heroic faith. The modern believer must have no mysteries but must have everything planed down to a scientific standard.

Brethren, having once discerned the voice of God, obey without question. If you have to stand alone and nobody will befriend you, stand alone and God will befriend you. If you should get the ill word of those you value most, bear it. What, after all, are ill words, or good words, as compared with the keeping of a clear conscience by walking in the way of the Lord? The line of truth is narrow as a razor’s edge; and he needs to wear the golden sandals of the peace of God who shall keep to such a line. Through divine grace may we, like Abraham, walk with our hand in the hand of the Lord, even where we cannot see our way! ~ C.H. Spurgeon
