"If our God is the same as the God of New Testament believers, how can we justify ourselves in resting content with an experience of communion with Him, and a level of Christian conduct, that falls so far below theirs? If God is the same, this is not an issue that any one of us can evade." pg 80

In the New Testament we have a picture of the church, and it is relevant to the church at all times and in all ages."
