Sharing how Galatians 6:15-16 does not in any place state that circumcision has been abolished – rather it is emphasising the importance of a person being made new (2 Cor 5:17).
This newness includes a new heart and God’s Holy Spirit causing a person to walk in His ways (Ezekiel 36:26-28, Acts 15:8-9, 2 Corinthians 5:17).
