The simple reality of the Christian faith is that it isn't easy. It isn't easy and as a result difficulty is often accompanied by doubt. How do I know I'm really a Christian? How do I even know all this God stuff is real? One of the things we need to keep talking about in the church is assurance. People need to be assured about their faith in the humdrum of life. The Philadelphian church was a struggling, but faithful church in desperate need of tender words of assurance. By listening to what Jesus says to them, we too can find the assurance we need to persevere in the Christian faith.
