Deuteronomy 28:15

But it shall come about, if you do not listen to and obey the voice of the Lord your God, being careful to do all His commandments and His statutes which I am commanding you today, then all these curses will come upon you and overtake you.

If they read the comparison between the blessing and the curse, most people wouldn’t choose the curse until it becomes a question of following the leadership of God and trusting in that leadership. If the devil deceives a person and distorts their view of God, that person will choose the curse. Without knowledge and examples of who God is from His people, the church, a change won’t come to the lost person.
