Acts 11:17
So if God gave them the same gift as he gave us, who believed in the Lord Jesus Christ, who was I to think that I could oppose God?”

Here Peter is speaking about the message he received from God who told him that faith in Jesus is for all people, not just the Jews. God leads the non-Jewish people (Gentiles) to faith in Christ and so it is legitimate. The barriers are falling and being right with God is possible for all cultures.

Pray for your Jewish friends.
