13 Do not have two differing weights in your bag—one heavy, one light. 14 Do not have two differing measures in your house—one large, one small. 15 You must have accurate and honest weights and measures, so that you may live long in the land the Lord your God is giving you. 16 For the Lord your God detests anyone who does these things, anyone who deals dishonestly. — Deuteronomy 25:13-16
Any creation model, any interpretation of Genesis 1-11, any challenge to the theory of evolution or the scientific consensus on the age of the Earth, must obey these verses. The age of the earth and evolution themselves are not important theologically, but teaching falsehood and misinformation in the name of Christ about any subject is a very serious matter. For this reason any form of creationism that does not obey these verses is not Biblical, is not scientific, and is not honest.
I work as a software developer in the south of England, currently building software for financial advisers. I read Natural Sciences at Cambridge University, studying physics in the Cavendish Laboratory. My father was a pastor, Bible teacher and theologian, who wrote a Bible course for Charismatic Christians called The Way of the Spirit.
