1-3 Now the apostles and the brothers who were throughout Judea heard that the Gentiles also had received the word of God. So when Peter went up to Jerusalem, the circumcision party criticized him, saying, "You went to uncircumcised men and ate with them."
18 When they heard these things they fell silent. And they glorified God, saying, "Then to the Gentiles also God has granted repentance that leads to life."
Even the early church struggled with not accepting those who were different are not part of their group. But hearing how God worked they realized His hand was in this. Sometimes God does things different than we expect in people we don't expect. But we need to listen and look for God's hand in it.
