God is the only One we should be viewing as vital, priceless, and irreplaceable. While we should certainly be respecting other humans as creatures who God places a high value on, at the end of the day, all created beings are expendable. We shouldn’t be viewing each other as our lifelines, because we’re so not. All human relationships are temporary at best, and most of the people we meet in this world will end up in Hell, thus eliminating any opportunity to develop positive relationships with them in eternity. Naturally we resist facing these facts, but ignoring them doesn’t make them go away. It is God who shapes reality for us, and the reality He’s made for us is one in which He is the only One who can be counted on to stay with us no matter what. He is the only One who can satisfy our souls, and He is the only One who is capable of taking care of us. So it is God we need to be depending on, trusting, and submitting to. When He takes loved ones before we want Him to, we need to focus our energy on respecting His right to do whatever He wants with His own property.
