They themselves will be convinced that we are right, for they will remember to what horrors of slavery and confusion your freedom led them.
Jews remembered always the bondage from which God delivered them. Reminders of the Exodus fill the Hebrew Bible, and Jews recall the event every year at Passover. The Jews did suffer slavery and chaos after Egyptian bondage, but at most they could say that this was the recurrence of slavery, not that God's gift of freedom, given at the Exodus, led them into slavery. As a nation, of course, Israel has always yearned for independence and freedom.
Christians have a different focus, centered on Jesus, but the Hebrew Bible is part of the Christian scriptures, and the Jewish tradition of choosing independence over slavery is part of the Christian DNA, though Christians have not always recognized this fact.
