Acts 15:9 and made no distinction between us and them, purifying their hearts by faith.
When the people in charge of the Jews and the Jewish customs and laws said that everyone had to be circumcised just as the Jews are, someone had to stand up and tell the truth.
When the disciples did so, they came up against the people in charge because it was a change to the laws; or so it seemed.
When God gave the people the Holy Spirit, it was because of faith in the belief and not because of human laws.
Trust God and believe in His word.
