Remain faithful with your whole heart

"When the time of David's death drew near, he gave these instructions to his son Solomon: "I am going the way of all mankind. Take courage and be a man. Keep the mandate of the LORD, your God, following his ways and observing his statutes, commands, ordinances, and decrees as they are written in the law of Moses, that you may succeed in whatever you do, wherever you turn, and the LORD may fulfill the promise he made on my behalf when he said, 'If your sons so conduct themselves that they remain faithful to me with their whole heart and with their whole soul, you shall always have someone of your line on the throne of Israel.' " (1 Kings 2: 1 - 4)

The above scripture reminds me of Joshua 1: 1 – 8.

"After Moses, the servant of the LORD, had died, the LORD said to Moses' aide Joshua, son of Nun: "My servant Moses is dead. So prepare to cross the Jordan here, with all the people into the land I will give the Israelites. As I promised Moses, I will deliver to you every place where you set foot. 1 Your domain is to be all the land of the Hittites, from the desert and from Lebanon east to the great river Euphrates and west to the Great Sea. No one can withstand you while you live. I will be with you as I was with Moses: I will not leave you nor forsake you. Be firm and steadfast, so that you may give this people possession of the land which I swore to their fathers I would give them. Above all, be firm and steadfast, taking care to observe the entire law which my servant Moses enjoined on you. Do not swerve from it either to the right or to the left, that you may succeed wherever you go. Keep this book of the law on your lips. Recite it by day and by night, that you may observe carefully all that is written in it; then you will successfully attain your goal. " (Joshua 1: 1 - 8)

The key to success is to listen to God and remain faithful to Him with one’s whole heart.
