The planets maintain their orbit around the sun because of the gravitational forces at work. Without the enormous mass of the sun, we would simply fly off into space in search for some new gravitational center. And that would result in the destruction of life on the planet. Life is maintained due to the link of the earth to the sun. There’s probably a lot more to it than that, but that’s what I remember from 4th grade science.
Romans 1:28-32 suggest that what is true in the physical realm is also true in the spiritual. Without the gravitational pull of God (the moral center), we fly off in search for a new moral center. The problem is that no other gravitational spiritual core can provide life. If we reject God, we reject order, stability and wholeness–peace. If we reject God, we will become gods for ourselves–doing whatever is right in our own eyes. If we reject God, we can expect a complete breakdown in our relationships with one another, our relationship with the rest of creation, our relationship to ourselves. And we all know where that path ultimately leads.
