Deuteronomy 30:19 I call heaven and earth to record this day against you, that I have set before you life and death, blessing and cursing: therefore choose life, that both thou and thy seed may live:
God wants His people to obey Him. He makes that abundantly clear. The nation and each individual must choose. God explained the options. He showed the consequences. Then He placed the responsibility squarely on His people.
Serving and obeying God would bring life for the parents and their children. Disobedience would bring the opposite. Moses calls heaven and earth to be his witnesses that this is what God is saying.
Today you must choose also. You can refuse to believe in God, the Lord Jesus Christ, and what He did on the cross. If you do, then you will be cursed. You can believe and obey, and you will be blessed with eternal life. What will your decision be?
