Like all great sermons, the Sermon on the Mount ends with an invitation, or the need to make choices. Having described life in the Kingdom of God, Jesus invites his followers in. Of course, the life he has described might seem undesirable. After all, he has called for love of enemies, the abandonment of lust, the renouncing of wealth as a goal. But Jesus has not yet told us why we should choose the kingdom. Now he does.
