Luke 23:33-43
The Cathedral of The Heart

The whole emphasis of the bible and of two thousand years of christians in ministry and worship is that this second birth of Jesus on the cross, as the first born of the dead, is all important - the purpose of His life.  But the first birth is important too, of course.  Its purpose is to let us know that Jesus began in exactly the same place we did, born of human mothers, and to draw our attention to this second birth, in the hope that we too will choose it.
