If you are insulted for the name of Christ, blessed are you; because the Spirit of glory and of God rests on you. On their part he is blasphemed, but on your part he is glorified.
Spirit of glory ...  Spirit of God ...  These are apparently synonymous; and, if so, they mean the Holy Spirit.  It was one of the glorious fruits of the indwelling Spirit in Christian hearts that produced the vast spiritual strength enabling the Christian to go on wearing the name, go on being a Christian, go on loving and believing Christ, in spite of being reviled and persecuted for it.
