Deuteronomy 30:20

20 You can make this choice by loving the LORD your God, obeying him, and committing yourself firmly to him. This is the key to your life. And if you love and obey the LORD, you will live long in the land the LORD swore to give your ancestors Abraham, Isaac, and Jacob.”

Deuteronomy 30:20 Meaning and Commentary

Deuteronomy 30:20

That thou mayest love the Lord thy God
And show it by keeping his commands:

[and] that thou mayest obey his voice;
in his word, and by his prophets:

and that thou mayest cleave unto him;
and to his worship, and not follow after and serve other gods:

for he [is] thy life, and the length of thy days;
the God of their lives, and the Father of their mercies; the giver of long life, and all the blessings of it; and which he had promised to those that were obedient, to him, and which they might expect:

that thou mayest dwell in the land which the Lord sware unto thy
fathers, to Abraham, to Isaac, and to Jacob, to give them;
the land of Canaan, often thus described; this was the grand promise made to obedience to the law, and was typical of eternal life and happiness; which is had, not through man's obedience to the law, but through the obedience and righteousness of Christ.

Deuteronomy 30:20 In-Context

18 then I warn you now that you will certainly be destroyed. You will not live a long, good life in the land you are crossing the Jordan to occupy.
19 “Today I have given you the choice between life and death, between blessings and curses. Now I call on heaven and earth to witness the choice you make. Oh, that you would choose life, so that you and your descendants might live!
20 You can make this choice by loving the LORD your God, obeying him, and committing yourself firmly to him. This is the key to your life. And if you love and obey the LORD, you will live long in the land the LORD swore to give your ancestors Abraham, Isaac, and Jacob.”
