If we have received Christ Himself in our inmost hearts, our new life will display its intimate acquaintance with Him by a walk of faith in Him. Walking implies action. Our Christian life is not to be confined to our closet; our belief must be revealed in our practice. If a man walks in Christ, then he must act as Christ would act; since Christ is in him--his hope, his love, his joy, his life--he is the reflection of the image of Jesus; and men will say of that man, "He is like his Master; he lives like Jesus Christ."
Walking signifies progress. "So walk in him." Proceed from grace to grace; run forward until you reach the ultimate degree of knowledge that a man can attain concerning Christ. Walking implies continuance. There must be a continual abiding in Christ.
Many Christians think that in the morning and evening they ought to come into the company of Jesus, but regard the rest of the day as their own: But this is poor living; we should always be with Him, treading in His steps and doing His will.
Walking also implies habit. When we speak of a man's walk and conversation, we mean his habits, the constant theme of his life.
Now, if we sometimes enjoy Christ and then forget Him, sometimes call Him ours and then lose our hold, that is not a habit; we do not walk in Him. We must keep to Him, cling to Him, never let Him go, but live and have our being in Him.
"Therefore, as you received Christ Jesus the Lord, so walk in him"; persevere in the same way in which you began, and, just as at the beginning Christ Jesus was the trust of your faith, the source of your life, the principle of your action, and the joy of your spirit, so let Him be the same until life's end, the same when you walk through the valley of the shadow of death and enter into the joy and the rest that remain for the people of God. O Holy Spirit, enable us to obey this heavenly precept.
