Biblical covenants sit at the heart of understanding God's promises and their fulfillment, particularly regarding the relationship between Israel and the Church. The evidence shows these covenants contain both conditional and unconditional elements. In the Abrahamic covenant, God unconditionally committed to fulfill certain promises, as seen when He alone passed between the sacrificial animals in Genesis 15. However, who receives these promises is conditional upon faith and obedience, as Genesis 17-18 clearly demonstrates.This dual nature challenges common eschatological assumptions. Those who inherit Abraham's promises are his spiritual descendants—those who, like him, follow God in faith. While this initially operated primarily within national Israel, it expanded to include Gentiles who demonstrate the same faith. Paul's writings in Galatians 3 and Romans 9-11 present a complex picture where 'Israel' refers to both natural Jews and spiritual believers, making it difficult to neatly separate these groups when interpreting prophecy. This understanding should foster humility in our end-times positions, focusing less on dogmatic timelines and more on the consistent principle that God's promises are received through the 'obedience of faith.'
