God's light is the light of how to live

Because when it does goodness, how do we know what to tell the truth is better than to lie? All of these things universally come from where? How does even a child know that to be kind is better than to be unkind? Although they do many unkind things, but we know somewhere that they're making a mistake. So where do all of that come from? Same presence. So God's light, God's presence also is the light bearer of how to live in the world.
