How does God perform the circumcision of the heart?

The circumcision of the heart is a supernatural work initiated by God alone. As indicated in the sermon, it is not accomplished through human effort or adherence to religious laws; rather, it is a divine act that occurs within the believer's spirit. Colossians 2:11 states that we are 'circumcised with the circumcision made without hands,' indicating that this transformation is a spiritual reality wrought by God. This process begins with God's sovereign decision and is expressed through regeneration, where He changes our hearts and enables us to respond to His grace. It is a work that often remains hidden initially, as the believer starts to understand their own state and the need for divine mercy and righteousness. Ultimately, this inward change leads to a genuine faith and response to the gospel.
