How do people who don't rely on God make it through life? What do they do when horrible things happen? Who do they turn to?
Not only do they not have God, they don't have the family that comes with the relationship to God: the church.
When one of our church members ends up in the emergency room or worse, we always get a call from someone in the family. That is something no one should have to face alone. After a call like that, one (or more) of our pastors is usually on the way to the hospital. And then the Sunday School teacher is there. And then other class members come by for support. And there are offers to pick up kids at school and spend the night if needed. There are hands to hold and shoulders to lean on or cry on.
Those hands and shoulders may look like they belong to friends, but they are really God's hands and shoulders. He puts us into the lives of others to hold each other up.
I can't imagine being alone when life happens. I'm glad I never have to be. I have His promise.
