And David perceived that the LORD had established him king over Israel, and that he had exalted his kingdom for his people Israel’s sake. 2 Samuel 5:12
SUGGESTED FURTHER READING: Esther 4

David knew to what end God had exalted his reign: it was because of his people, Israel. David could easily have thought that God was making him prosper to maintain him as ruler over the kingdom. But to know the intention of God and to what end he does something takes far more prudence. David perceived that God was exalting him because of his people Israel. So David knew the reason why he was reigning. It was not for his personal profit but for the common salvation of all.
This is well worth noting, for we must always remember that it is not enough for us to recognize the blessings of God. We must also always use those properly. How? When God has brought us back from some illness, when he has saved us from some danger, we must realize that he does this so we might thank him and honor his name. Moreover, let us realize that we must apply everything we are granted to his service.
In sum, let us learn that, whenever God shows mercy to his people or to an individual member of the body, it is so that we will call on him and recognize him as the author of every good, then give ourselves to his service and dedicate all that we have to it.
On the other hand, when I see that God has set me apart for some service, I must realize that it is not because of me that he has prolonged my life but because he wants to use me in the service of his church. This is the prudence we should manifest whenever God favors us. Let us realize that these blessings are not to be useless but always think: God has preserved me so many times. I must, therefore, show that I am aware of this.

FOR MEDITATION: God has determined roles for each of us to fill within his plan. He has given us specific gifts and blessings to suit us for the task we must do. We should study God’s Word and the way Christ is leading us and consult with other believers to determine how to best use the gifts he has given us for his service.
