Christ, in this vision, useth two arguments to persuade Paul to continue preaching the gospel at Corinth:
1. Because he would be with him, to supply, support, and deliver him; as it is promised to Jeremiah, Jer_1:19, and to all the faithful ministers of Christ, Mat_28:20. This promise was fulfilled to Paul, and to other of God’s servants; whatsoever troubles they met with, even when they were killed, they were not hurt, Rom_8:36-39.
2. The other reason why Paul was commanded to tarry was, because there were many that God would have called by his ministry; and thus those who were not his people God calleth his people, as Hos_1:10 2:23.
