John Chrysostom

"Wherefore," saith he, "my brethren, beloved and longed for, my joy and crown, so stand fast in the Lord, my beloved."

"So." How? Unmoved. See how he addeth praise after exhortation, "my joy and my crown," not simply joy but glory too, not simply glory but my crown too. Which glory nought can equal, since it is the crown of Paul. "So stand fast in the Lord, my beloved," i.e. in the hope of God.
