What does the term 'spiritual Israel' mean?

'Spiritual Israel' signifies those who are part of the true covenant community of God, encompassing both Jewish and Gentile believers united in faith through Jesus Christ. Romans 9:7-8 clarifies that not all physical descendants of Abraham are children of God; rather, the children of promise are those who believe in Christ. Galatians 3:29 reinforces this notion, stating that if we belong to Christ, we are heirs according to the promise made to Abraham. Therefore, spiritual Israel is defined by faith, not lineage.
