As ye have therefore received Christ Jesus the Lord, so walk ye in him:
Rooted and built up in him, and stablished in the faith, as ye have been taught, abounding therein with thanksgiving.
(Colossians 2:6-7 KJV)
Let me ask you only this: Did you receive the Spirit by works of the law or by hearing with faith? Are you so foolish? Having begun by the Spirit, are you now being perfected byfn the flesh?
“If you would know how faith is to be exercised in thus abiding in Jesus, to be rooted more deeply and firmly in him, you have only to look back to the time when first you received him. You remember well what obstacles at that time there appeared to be in the way of your believing. There was first your vileness and guilt: it appeared impossible that the promise of pardon and love could be for such a sinner. Then there was the sense of weakness and death: you felt not the power for the surrender and the trust to which you were called. And then there was the future: you dared not undertake to be a disciple of Jesus while you felt so sure that you could not remain standing, but would speedily again be unfaithful and fall. These difficulties were as mountains in your way. And how were they removed? Simply by the word of God. That word, as it were, compelled you to believe that, notwithstanding guilt in the past, and weakness in the present, and unfaithfulness in the future, the promise was sure that Jesus would accept and save you. On that word you ventured to come, and were not deceived: you found that Jesus did indeed accept and save you.
Apply this, your experience in coming to Jesus, to the abiding in him. By faith you became partakers of the initial grace; by that same faith you can enjoy the continuous grace of abiding in him.”
—Andrew Murray (quoted in Spurgeon’s Sermon Notes, Part IV.)
