The Keys of Restoration (Galatians 6:1-5 (LD 31)

The kingdom of God is something that is strong and powerful.  It is something that is also exclusive in the sense that not everyone is found in this kingdom, but only those who are Christians.  So, how does one get into this kingdom?  Why should someone want to be in this kingdom?  Are there benefits to being in this kingdom or not? What should the church do if someone is living a life that excludes them from the kingdom?
