Moses showed the consequences of our decisions in his last speech in Deuteronomy.

Moses says in Deuteronomy 30:19-20, “Choose life, that you may live, loving the Lord your God, obeying his voice and holding fast to him, for he is your life.”

The possibility of choosing between life and death goes like a red line through the Bible. It begins in the Garden of Eden with the two trees. Jesus speaks of eternal life and perdition. And in Revelation, humanity reaps the consequences of their choices.

In short, those who love God will live, those who oppose him will perish. God has mercy on those who turn back.

Deuteronomy 30:2 If you return to the Lord your God, you and your children, and obey his voice in all that I command you today, with all your heart and with all your soul, 3 then the Lord your God will restore your fortunes and have mercy on you, … 6  so that you will love the Lord your God with all your heart and with all your soul, that you may live.
