What does it mean to be part of the Israel of God?

The term 'Israel of God' refers to the true people of God, who have experienced the inward transformation brought by the Holy Spirit. As indicated in the sermon, this Israel transcends the physical lineage of Abraham and includes all those who have been born again. The Apostle Paul articulates this in Romans, where he notes that true circumcision is a matter of the heart, prepared by the Spirit. Thus, the Israel of God is characterized by a deep relationship with Christ, marked by faith, repentance, and a reliance on God's grace. They are viewed as a peculiar people, set apart to witness to God's glory and grace in the world.
