What meant that "Me"? It meant that the persecuted saints were every one of them united to Christ in glory by the Spirit who dwelt in them: they were members of His Body, that which He accounts to be Himself, even as He had become their life. There had been nothing like this before. The assembly had been formed into this relationship at Pentecost, but this was the first intimation of it: the whole truth of it was involved in the words that fell so strangely from heaven upon the ears of Saul. It was, in principle, the Mystery, which was ever after to characterise his ministry; even as the Lord had further to say to him, "I have appeared unto thee for this purpose, to make thee a minister and a witness both of these things which thou hast seen, and of those things in the which I will appear unto thee" (Acts 26:12-16).
