What we see here today marks a turning point, and now the church is ready to explode outward! A whole group of Gentiles convert to Christianity, and the Gentile church is likely established. The gospel spreading to the Gentiles shows to them, that there is no border for Christ! Whether geographical, ethnic, cultural, whatever! There is no square inch that is off-limits to him and there is no people or person that is not of interest to him or beyond his reach.
What we learn is that there is no border control for Christ – when people come to enter into his Church, they don’t hold up an ID badge that proves they are this type of person or that type, where some are let in and some aren’t based on how they look or where they’re from. The ONLY ID badge that anyone needs is faith in Jesus; and if they have that then they need nothing else!
