I am astonished that you are turning away so quickly from the one who called you by the grace of Christ to a different gospel,

not that [there] is a different [gospel], except there are some who are disturbing you and wanting to distort the gospel of Christ.

Now I say, for as long a time [as] the heir is a child, [he is] no different from a slave, [although he] is master of everything,

I have confidence in you in the Lord that you will think nothing different, but the one who is confusing you {will pay the penalty}, whoever he may be.
