In the beginning, God promised us He would be our God as long as our hearts were toward Him (1). Our changed hearts are signs that we repented from evil deeds. Changing our hearts shows that we want to be God’s. This desire for a relationship, between God and humans, goes two ways: 1) The promise is that we can be God’s and 2) That we should show that we want to be God’s by a changed heart.

A Caring God

When people are God’s people, God takes care of them. Being God’s means that God takes possession of us. He, like a mother, nurtures, protects, and encourages us. He is like the mother watching her daughter play a basketball game; the mother cares for her daughter’s safety, helped the daughter get ready for the game by washing her daughter’s jersey, and shouts during the game to encourage her daughter. The daughter takes comfort in her knowing that she has a mother like this. We can take similar comfort in God because God tells us “Fear not, for I am with thee: be not dismayed; for I am thy God: I will strengthen you. I will help you. I will uphold you with my right hand of righteousness” (2).

No Other God

When we have God and God has us, we don’t need another God because God is enough “God” for us. If we look at the example of the caring mother and the nurtured daughter, we should see that the nurtured daughter has no reason to want another mother. Her mother is enough because the mother gives the daughter what the daughter needs. If I have a God who cares, protects, and strengthens me, why do I need another god? I don’t. When I have a God who loves me so much to “be merciful to my unrighteousness and forget my iniquities,” what other god do I need? If I have a God who gives me eternal life, what other god should I seek? None.

When we belong to God, we show that we are His from our behavior. He takes care of us, and we have no desire for another god. When God is ours, “we have everything” (3).
