Do we believe in a “timeless” church?

This post was prompted by a comment made by my brother over here. I understand that the way of God is one eternal round and that he is the same yesterday, today, and forever. But I don’t think those things mean what they seem to mean at face value. For two reasons:

1) If God is static, whence eternal progression?
2) If the Gospel is static, whence the need for continuing revelation?

Discuss.
