Deuteronomy 30:20

20 loving ADONAI your God, paying attention to what he says and clinging to him - for that is the purpose of your life! On this depends the length of time you will live in the land ADONAI swore he would give to your ancestors Avraham, Yitz'chak and Ya'akov."

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.

18 I am announcing to you today that you will certainly perish; you will not live long in the land you are crossing the Yarden to enter and possess.
19 "I call on heaven and earth to witness against you today that I have presented you with life and death, the blessing and the curse. Therefore, choose life, so that you will live, you and your descendants,
20 loving ADONAI your God, paying attention to what he says and clinging to him - for that is the purpose of your life! On this depends the length of time you will live in the land ADONAI swore he would give to your ancestors Avraham, Yitz'chak and Ya'akov."
