'Grace of God' in the Bible

And being also co-laborers we exhort you not to receive the grace of God in vain,??2 for he says, In an acceptable time I heard you, and in a day of salvation I helped you; behold, now is an acceptable time, behold, now is a day of salvation,??3 giving no offense in any thing, that the ministry may not be blamed,

AND I make known to you, brothers, the grace of God given to the churches of Macedonia,

and by their prayer for you, greatly longing for you on account of the abounding grace of God upon you.
