I'm afraid that the answer to my question might be obvious; if so, then it'll be answered quickly!
I come from a Christian background which told me that God has forgiven all of my sins, past, present, and future. I also come from a background which tells me that I should ask God for forgiveness. I also have the background belief that it's not the case that you should ask for what you already have. These beliefs seem to me to conflict. Let's be more precise.
1) At t, God has already forgiven me for the sin I committed shortly before at t-1.
2) At t, I ought to ask God for forgiveness for the sin I committed shortly before at t-1.
3) It's not the case that I ought to ask for something that I believe that I already have.
I think that both the "moral" and "rational" oughts apply in (2), but let's suppose that it's a "rational" ought. Now suppose I believe (1). Then, if I believe (3), it follows that I don't think I ought to ask for forgiveness. But then it follows that I should reject (2). So belief in (1)-(3) leads me to have an irrational set of beliefs.
So I should give one up. Here's what might be obvious to some that's not obvious to me. Which one should I give up?
