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

Why ought we to walk as Jesus did?

When we read the word “ought,” if we are honest men, we begin to look about us and to make enquiries as to the reason and the measure of this obligation. An “ought” is a compulsion to a true heart. There is a “needs be” to every godly man that he should do what he ought.

What, then, is the ground upon which this “ought” is fixed?

It is a part of the original covenant purpose; for “whom He did foreknow He also did predestinate to be conformed to the image of His Son.” That is the drift of the plan of grace, the aim of the covenant. Grace looks towards holiness, that there should be a people called forth to whom Christ should be the elder brother, the firstborn among many brethren. You certainly have not had the purpose of God fulfilled in you, dear friend, unless you have been conformed to the image of His dear Son. “He hath chosen us in Christ Jesus before the foundation of the world, that we should be holy and without blame before Him in love.” This is the aim of election; this is the object of redemption; this is the fruit of calling; this is the concomitant of justification; this is the evidence of adoption; this is the earnest of glory; that we should be holy, even as Christ is holy, and in this respect should wear the lineaments of the Son of God. He hath given His own Son to die for us, that we may die to sin; He has given Him to live that we may live like Him. In every one of us the Father desires to see Christ, that so Christ may be glorified in every one of us. Do you not feel this to be an imperative necessity to be laid upon you? Would you have the Lord miss His purpose? You are chosen of God to this end, that you should be “a chosen generation, a royal priesthood, a holy nation, a peculiar people, zealous of good works,” and what is this but that you should walk even as He walked? ~ C.H. Spurgeon
