But there is more than that in the Apostle's mind. He was accustomed to quote the fact that he, the persecutor, had been made the messenger of Christ, as a living proof of the infinite mercy and power of that ascended Lord, whom his eyes saw on the road to Damascus. So here, he puts stress on the fact that he _became_ a minister of the gospel, as being an "evidence of Christianity." The history of his conversion is one of the strongest proofs of the resurrection and ascension of Jesus Christ. You know, he seems to say, what turned me from being a persecutor into an apostle. It was because I saw the living Christ, and "heard the words of His mouth," and, I beseech you, listen to no words which make His dominion less sovereign, and His sole and all sufficient work on the cross less mighty as the only power that knits earth to heaven.
So the sum of this whole matter is--abide in Christ. Let us root and ground our lives and characters in Him, and then God's inmost desire will be gratified in regard to us, and He will bring even us stainless and blameless into the blaze of His presence. There we shall all have to stand, and let that all-penetrating light search us through and through. How do we expect to be then "found of Him in peace, without spot and blameless"? There is but one way--to live in constant exercise of faith in Christ, and grip Him so close and sure that the world, the flesh and the devil cannot make us loosen our fingers. Then He will hold us up, and His great purpose, which brought Him to earth, and nailed Him to the cross, will be fulfilled in us, and at last, we shall lift up voices of wondering praise "to Him who is able to keep us from falling, and to present us faultless before the presence of His glory with exceeding joy."
