Friends become wiser together through a healthy clash of viewpoints.
If you and your church were to disappear off the face of the earth tomorrow, would anyone in the community around you notice you were gone? And if the community did even notice would they say 'we are really glad they are gone', or 'we are really going to miss them'?
If you don't love the poor, you don't know what God's done for you.
What you do in secret tells you who your God is.
If you need something in addition to God to make you happy, that is your true King.
You can't live the Christian life without a band of Christian friends, without a family of believers in which you find a place.
