This picture represents the doctrine "we were made to be a family" not only because it depicts more than one person, but also because everyone is holding hands. This makes more clear that what affects one affects all.
This is true throughout the earth because, in heaven, all of us will be richer fo the holiness of each of us.
We can picture this in terms of light. In heaven, each of us will shine according to our holiness. But the light from each of us will give more light to all
We know that this is true for five reasons: One, that all of us are richer for the goodness of each of us is how life already works here. Two, clearly we were made for sharing. Three, sharing is certainly what our love will do once we can see the good that God has put in everyone. Four, all of us already owe others for who we are. And, Five, the doctrine “we were made to be a family” makes sense of everything else we see and believe.
The doctrine "we were made to be a family":
tells us a lot about what heaven will be like, assuring us that we will be together with the people whom we love.
It shows us that love is smart in every way. After all, not only are all others people we will love as brothers and sisters, we are all going to be richer for everyone we help to grow. Besides this, the doctrine makes sense of self-sacrifice, something that otherwise makes no sense.
Finally, it helps us to see the wisdom of God’s plan when someone gets a life which was short, misfortunate, or troublesome. Such lives still affect others and thus they play an essential role in the creation of the family that we were meant to be. Case in point: The death of infants. Here are people who had little chance to grow. Nonetheless, their deaths affect others. These others affect others, who affect others, who affect others. By this process, if sometimes slowly, the holiness of our family will grow. And those whose lives led to this holiness will share in the fruits of it.
