Both Abraham and Jesus spread their beliefs during a time of uncertainty: Abraham's people had no homeland before Canaan, and the Jewish people in Jesus's day faced occupation of their homeland by the Romans.
Jews believe in individual and collective participation in an eternal dialogue with God through tradition, rituals, prayers and ethical actions. Christianity generally believes in a Tribune God, one person of whom became human. Judaism emphasizes the Oneness of God and rejects the Christian concept of God in human form.
