I'm not sure if there were dinosaurs on the ark with Noah. They don't get a shout out in Genesis 7. None of the verses specifically say, "And then, with great difficulty, Noah captured a T-Rex and was able to strap him down in the basement of the ark."
But I do think that this section of Genesis is one of those Velcro places in the Bible. People get stuck here and argue here about the intricacies of the story. They discuss whether dinosaurs were on the ark, how old the earth is, where science and faith intersect.
I have to confess that I'm not an expert on a lot of that. I think it's a perfectly legitimate thing to discuss and I think God smiles when we learn and explore His truth and the nuances of it with the brains He gifted us with. I think that there is great beauty in understanding science and seeing God's fingerprints on the things we experience in this world from a biological, physical sense. I applaud the many people that use this approach as a way to engage people that don't know the Lord. I don't however think God's cool when we get stuck on any one particular issue.
With me, that issue isn't evolution, it's porn. I often rail against that topic, trying to get people and churches to see it as a problem and start working toward a plan to combat what I feel like is an out of control monster. But sometimes, I focus too much on the specifics of that issue and not enough on the actual people that are struggling with it.
What if we kept faith simple instead? What if the only things we got stuck on was loving God, loving others and loving ourselves? The other day I admitted, it's easier to traffic in ideas than it is to love people. People are messy and difficult to understand. An idea can be put in a box and controlled to an extent, mastered even a little. But until I've got my love for God, my love for others and my love for me (perhaps the hardest of the three) humming along nicely, I probably shouldn't get lost trying to figure out whether there was a brontosaurus on the ark or whatever happened to all the unicorns.
