Creation Days Controversy

This morning in Sunday School I heard a great summary of John C. Collins exegesis of the nature of the creation days. Collins believes in verbal, plenary (full) inspiration of Scripture, and in literal or authorial intent interpretation of the Bible. Collins also believes that the creation days of Genesis 1 are not 24 hour solar days but our 24 hour solar days are analogical to the days of creation.  Dr. Collins is a former prof of mine at Covenant seminary and I had heard his argument before but this crystallized it for me. The basic argument runs as follows:

1. The Hebrew word for day "yom" is not a technical term for a 24 hour solar day. Genesis 2:4 refers to the entire week of creation as a "yom."
   
2. We are still in the seventh day. The refrain "evening and morning" occurs at the end of each creation day and refers to the period of rest between the periods of work. This refrain does not occur on the seventh day, which shows that God is still at rest. Thus the seventh day is ongoing and not a 24 hour solar day. Hebrews 4:3-5 confirms this interpretation saying that "God rested on the seventh day from his all works" but disobedient Israel cannot enter his rest. Augustine, who was obviously not trying to make peace with Darwinism, pointed this out in his Confessions. He said that since God is still in his seventh day we can enter his rest by faith. 
3. God's creation days are analogical. They set the pattern for our 24 hour solar days. Since God rested the "evening and morning" of each day so should we. Since God rested on the seventh day so should we. Just like our creating is based on God's creating without being ex nihilo (out of nothing), so our days are like his without his necessarily being 24 hours long.
4. The best way to harmonize Genesis 1 and 2 is to assume the days of Genesis 1 are analogical. It is hard to imagine Adam getting lonely within the first day given all the work he had to do tending the garden and naming the animals.
