By faith Abraham, when he was called to go out into a place which he should after receive for an inheritance, obeyed; and he went out, not knowing whither he went. – Hebrews 11:8

Whatever the Lord may have said to the Chaldeans, or to other families in Ur, Abraham was not so much concerned with that as with the special word of command which the Lord had sent to his own soul. Oh, that we were most of all earnest to render personal obedience! It is very easy to offer unto God a sort of “other people’s obedience”-to fancy that we are serving God, when we are finding fault with our neighbours, and lamenting that they are not so godly as they ought to be. Truly, we cannot help seeing their shortcomings; but we should do well to be less observant of them than we are. Let us turn our magnifying glasses upon ourselves. It is not so much our business to be weeding other people’s gardens as to keep our own vineyard. To the Lord each one should cry, “Lord, what wilt Thou have me to do?” We, who are His chosen, redeemed from among men, called out from the rest of mankind, ought to feel that if no other ears hear the divine call, our ears must hear it; and if no other heart obeys, our soul rejoices to do so. We are bound with cords to the horns of the altar. The strongest ties of gratitude hold us to the service of Jesus: we must be obedient in life to Him who, for our sakes, was obedient unto death. Our service to our Lord is freedom: we will to yield to His will. To delight Him is our delight. It is a blessed thing when the inmost nature yearns to obey God, when obedience grows into a habit, and becomes the very element in which the spirit breathes. Surely it should be so with every one of the blood-washed children of the Most High, and their lives will prove that it is so. Others are bound to obey, but we should attend most to our own personal obligation and set our own houses in order. Our obedience should begin at home, and it will find its hands full enough there. ~ C.H. Spurgeon
