What’s Your Datum?

I was talking to the steel fabricator recently on a multi-story project where I was designing the stairs for them, and their detailer told me, “Hold off on the stair calcs; there’s gonna be some changes coming.” What were the changes? The architect had used the wrong datum, or elevation reference, to match up the floors of this 3 story  expansion with the existing 5 story building it would be attaching to. In so doing, each of the floors, as well as the total height of the expansion, would be over 1 foot short. Fortunately, it was caught before steel was fabricated and shipped to the site. And as far as errors go, it could’ve been worse, in that most of the framing wouldn’t change. The floor plans would stay the same, the heights between floors weren’t affected – just the total column heights and the distance from the foundation to the first elevated floor. For me, the stairs would get longer on the first 2 flights, but otherwise a minimal impact at that stage. But if they’d tried erecting the steel with everything fabricated based on the wrong datum, none of the connections to the existing building would’ve lined up.  One simple assumption in their Revit building model would’ve been an expensive fix at that point.

This got me thinking. What datum do we build our lives on? Are we making assumptions that will cost us dearly later? Will we recognize those errors before it’s too late? One “reference datum” of special importance in our lives is our assumption of God’s existence or non-existence. This has dramatic ramifications in all areas of our lives because it is a foundational assumption. However, sometimes we don’t see those effects without careful investigation. For instance, in the project I had, the floor to floor heights on the upper levels were unaffected. If they had managed to finish building with that error incorporated, you wouldn’t notice it out in the middle of the 2nd or 3rd floor. Likewise, atheists often feel that they don’t need God to live a “good” life. In their day to day lives, they may feel there’s no real difference. The problem is that their worldview is missing some support. What would happen if we went down to the ground level of atheism and inspected its foundation? Under western atheism, we’d find some Bibles stuck under their “columns” as shims! Yes, to be livable (in a civilized manner), atheism has to be shimmed up by blocks of Christianity (or at the very least theism, but more typically Christianity).[1] Yet these are the very foundation blocks atheists try to demolish. For instance, an atheist can choose to ignore the fact that truly fair, objective judgement between humans requires a 3rd party outside of humanity (i.e. God). But when they succeed in removing that idea from the culture around them, they unintentionally undercut their own life structure. Atheists can try to ground their treatment of others in concepts like “human flourishing”, but only the God of the Bible gives us a reason for why we should treat others with dignity: we are made in God’s image – His unique creation – and we have intrinsic worth because of that. So even if I flat-out hated somebody, even if they were absolutely cruel to me, they are still a living soul made in God’s image, whom He considered worthy of Jesus’ sacrifice on the cross on their behalf. Then, whether or not they deserve my kindness, whether or not humanity flourishes because of my kindness to them, and whether or not it improves the situation any, there are grounds for treating that person with kindness, respect, and love. I’m not saying atheists can’t behave well, and do wonderful things, but at some point, in your personal relationships, where general abstract philosophizing becomes very real and messy, you could care less whether humanity flourishes if it means suffering some wrong you deem “too far.” Like with Corrie ten Boom forgiving her Nazi concentration camp guard, only God can provide a foundation capable of bearing all things and enduring all things [1 Cor 13:4-7].

What are you assuming as a “given” in your life? Have you investigated that to confirm what you’re building your life on? I’ve used terms like “assumption” and “given” today to describe our different worldviews, because that is how many people arrive at them. But don’t be content to stay there, living an unexamined life. Just like with the datum on the project I was working on, you too can investigate and determine whether the datum of your life is correct or not. I’ve highlighted several lines of reasoning on this site in the past to help show how God fulfills critical requirements for any valid reference datum in life. The moral argument shows God is necessary for objective morality. The cosmological argument shows how God is necessary to provide the singular beginning of all space and time that science predicts. The argument from design shows show God is necessary to explain the intelligent and purposeful contingency we see in our universe. And the ontological argument shows how God is necessary based on the very nature of existence. Dig deep, investigate, don’t be afraid to ask tough questions, and follow the evidence where it leads. In the end, you’ll find life makes a lot more sense with God as your absolute reference.

[1] Western atheists would do well to study the history of the USSR and communist China to see atheism carried closer to its conclusion, in grand scale, than perhaps anywhere else on earth. The tens of millions dead (some estimates say over 100 million) show that ideas like atheism can have very tragic and uncivilized consequences.
