on young/old earth...
To address the earlier questions on young/old earth, biblically...
1.) On "apparent age"-- the idea that God created everything in a way that necessarily looked like it was more than a minute "old"-- it's interesting to note that Jesus' first miracle (recorded in John 2, just after the reference to Jesus as deity and Creator in John 1) is to turn water into wine, creating something with apparent age.
2.) Someone made reference to reading Genesis, a *really* rich book. Leon Kass taught it at Chicago for decades as a "great books" course and his amazing book, The Beginning of Wisdom, came out of those efforts. If you're doing a study of Genesis and can handle a big book, it's a must read.
3.) There are many ways to get to an "old earth", biblically:
a.) Hab 3:6, II Pet 3:5 seem to imply an old earth (is the earth 120 hours older than Adam?);
b.) Adam's *really* busy "sixth day";
c.) recognition that the Hebrew word for "day" is used a half-dozen ways just in the first chapter plus of Genesis;
d.) "literary theories" on various ways to read Genesis 1-11 more broadly (I'd recommend Jewish scholar Nahum Sarna's Understanding Genesis here);
e.) John Walton on the connection of the Creation story in Genesis 1 to the Temple (he's interviewed in CT on this, but his book is good-- here's my blog post on it).
Bottom line: the age of the Earth should not be a stumbling block for those considering entry into the goodness of God's Kingdom.
