Deut 30:15See, I set before you today life and prosperity, death and destruction.
16For I command you today to love the Lord your God, to walk in obedience to him, and to keep his commands, decrees and laws; then you will live and increase, and the Lord your God will bless you in the land you are entering to possess.
17But if your heart turns away and you are not obedient, and if you are drawn away to bow down to other gods and worship them,
18I declare to you this day that you will certainly be destroyed. You will not live long in the land you are crossing the Jordan to enter and possess.
19This day I call the heavens and the earth as witnesses against you that I have set before you life and death, blessings and curses. Now choose life, so that you and your children may live
20and that you may love the Lord your God, listen to his voice, and hold fast to him. For the Lord is your life, and he will give you many years in the land he swore to give to your fathers, Abraham, Isaac and Jacob.
You notice that this has nothing to do with eternity; this is about the Israelites as a whole and their lives in the promise land, whether it will be good and prosperous or cursed by hardship. There are both temporal and eternal aspects to our actions.
