The Big Picture

So, here at Samford, I am taking a Biblical Perspectives class. It is a core requirement. I feel as though this class could be interesting, but I took the wrong professor. He likes to be very controversial and force his ideas on his students instead of teaching what we are supposed to learn. But, that is an entirely different blog.
I had a project/presentation that I had to present along with one of my friends today. We had to focus on one main idea from the reading that was assigned. Easy enough. (It was from Peter Enns' book Inspiration and Incarnation- Evangelicals and the Problem of the Old Testament for those of you who might be curious.) The portion that I had to do my assignment on was about Moses' Egyptian Education. The section was on why Stephen, in Acts 7 specifically talks about Moses receiving an Egyptian education, when the Old Testament never exactly says this, it is only implied.
I kept thinking to myself, this is really stupid. Why do I have to sit here and waste my time arguing about something as irrelevant as this? I mean seriously, this is what I am going to spend my time on? Whether or not Moses received an excellent Egyptian education because the Old Testament doesn't say it word for word? What happened to the bigger picture? Why are Christians (yes, this is a big generalization I know) focusing on these minuscule things? Why can't we focus on the bigger picture? That Jesus Christ died on the cross for the entire world so that we might have the opportunity to spend eternity with Him. Why aren't we putting our energy into something worth while, like spreading this good news? And loving God and other people to our best ability?
This is a really long and round about way to say that I think that Christian of every denomination (Presbyterian, Methodist, Catholic, Baptist, etc.) have all gotten a little off track. That we are sitting here arguing the little things, when the big picture is the reason why we are here and where we find our purpose. (I also understand that sometimes the little things are important, but in certain contexts.) If we could all just focus on our purpose and passion for Christ, I think there would be a lot less arguing in the world, so that we can invest our time to and our lives in the BIG PICTURE.
