When is Enough enough?

Its been a while hasn't it? The summer has gone so quickly and I seem to have filled up my time by doing... not a lot. Over the last few weeks I've been thinking about this question; in terms of our Christian Faith, when is enough enough?

I guess I'm asking this for a number of reasons. First of all I recently attended the banner of truth conference in Leicester. It was awesome. I learnt a lot and had a really good weekend. However I think its fair to say that for a lot of the time I felt out of my depth, by a long way. I was surrounded by academics who knew way more that me about everything Christianity related. This got me to tihnking that even if I devoted my whole life to the study of scripture I would probably never know or be as wise as these men. Is that OK? Should I want to? Should I just be content to not really get stuff but to understand what I need to for salvationa and try to live it out as best I can? To be a shining light to the world serving people but not really being bothered about heavy, academic theology or should we all be striving to be the next John MacArthur or Sinclair. B. Ferguson?

Secondly what exactly is required for salvation? Ye its sems a simple question doesn't it. A belief in a bibical gospel. That Jesus was the Son of God who came to earth to die for us and to take the punishment we deserve for our sin so that our relationship with God can be restored. Grace. (OK so that VERY simple but you get the idea). BUT what about things like limited atonement or the sovereignty of God? Christians believe vastly different things about these issues... for instance my views are quite different to my Dads but I don't doubt his Christianity for one second. Whats that about? What is it ESSENTIAL to believe for salvation and what are the issues that we can put to one side and say are secondary?

I'm a simple man. I like simple things. But, when it comes to my faith is it OK to be... simple? Thoughts anyone?
