The altitude under opposition and criticizing

Acts 10:44-11:10
The circumcised believers who had come with Peter were astonished that the gift of the Holy Spirit had been poured out even on the Gentiles.
When Peter went up to Jerusalem, the circumcised believers criticized him and said, "you went into the house of uncircumcised men and ate with them."
Peter explained everything to them precisely as it had happened.
No one can now deny baptism to those who have received such an obvious mark of God's favor.
The recounting of the events at Caesarea underlines their significance. The criticism Peter faces from a particularly narrow faction of Jewish Christians in Jerusalem will do every stage of Paul's missionary work.
Why?
It is the truth that God gave Holy Spirit on the gentiles in Caesarea, can anyone higher than God? No, We have to obey the authority of the Lord.
Peter explained it clearly to Jews Christian in Jerusalem. It is not Peter's power or his high position in church but it is the truth.
Under opposition and criticizing we have to calm down and explain it clearly without flesh word and mind but the experience and the truth, let others know the truth.
How?
Pray to the Lord give me the love and wisdom to love my enemy and those who oppose to me.
