Wow, you're right, that is harder than I thought. I think I'll go with the most recent, that way I don't have to try and determine which was the most important:
I thought that because of my financial situation, I wouldn't be able to attend school this semester, but this morning I found out that God has made a way for me to attend! Now that may seem small, but it is just showing God's hand ordering the events of my life. I'm excited!
