My success comes from wholeheartedly following God

Deuteronomy 30:9-19

The LORD your God will make you prosperous in all the work of your hand, in the fruit of your body, in the fruit of your livestock, and in the fruit of your ground, for good; for the LORD will again rejoice over you for good, as he rejoiced over your fathers, if you will obey the LORD your God’s voice, to keep his commandments and his statutes which are written in this book of the law; if you turn to the LORD your God with all your heart and with all your soul. For this commandment which I command you today is not too hard for you or too distant. It is not in heaven, that you should say, “Who will go up for us to heaven, bring it to us, and proclaim it to us, that we may do it?” Neither is it beyond the sea, that you should say, “Who will go over the sea for us, bring it to us, and proclaim it to us, that we may do it?” But the word is very near to you, in your mouth and in your heart, that you may do it. Behold, I have set before you today life and prosperity, and death and evil. For I command you today to love the LORD your God, to walk in his ways and to keep his commandments, his statutes, and his ordinances, that you may live and multiply, and that the LORD your God may bless you in the land where you go in to possess it. But if your heart turns away, and you will not hear, but are drawn away and worship other gods, and serve them, I declare to you today that you will surely perish. You will not prolong your days in the land where you pass over the Jordan to go in to possess it. I call heaven and earth to witness against you today that I have set before you life and death, the blessing and the curse. Therefore choose life, that you may live, you and your descendants.
