He that saith he abideth in Him ought himself also so to walk, even as He walked. – 1 John 2:6

Take care that you do not in all things copy any but Christ; for if I set my watch by the watch of one of my friends, and he sets his watch by that of another friend, we may all be wrong together. If we shall, each one, take his time from the sun, we shall all be right. There is nothing like going to the fountain-head. Take your lessons in holiness, not from a poor erring disciple, but from the infallible Master. God help you to do so.

You know what we did when we went to school. Our schoolmasters were not quite so wise then as schoolmasters are now. They wrote at the top of the page a certain line for us to follow, and a poor following it was. When I wrote my first line I copied the writing-master’s model, but when I wrote the next line I copied my copy of the top line; so that when I reached the bottom of the page I produced a copy of my copy of my copy of my copy of the top line. Thus my handwriting fed upon itself, and was nothing bettered but rather grew worse. So one man copies Christ, perhaps; a friend who hears him preach copies him, and his wife at home copies the hearer, and somebody copies her; and so it goes on all down the line, till we all miss that glorious hand-writing which Jesus has come to teach us. Keep your eye on Christ, dear brother. Never mind me: never mind your friend: never mind the old doctor that you have been hearing so long. Look to Jesus, and to Him alone. We have had our sects and our divisions all through that copying of the lines of the boys, instead of looking to the top-line that the Master wrote. “He that saith he abideth in Him ought himself also so to walk even as He walked” May the Spirit of God cause us to do it! Amen and Amen. ~ C.H. Spurgeon
