'Free' in the Bible

But Peter said to him, “May your money be destroyed along with you, because you thought you could buy the [free] gift of God with money!

All the circumcised believers who came with Peter were amazed, because the gift of the Holy Spirit had been poured out even on the Gentiles.

But with regard to the Gentiles who have believed [in Christ], we have sent them a letter with our decision that they should abstain from meat sacrificed to idols and from [consuming] blood and from [the meat of] what has been strangled and from sexual immorality.”
