Ding ding ding! We have a winner! You are 100% correct: I am an INFJ. Nice job, I am duly impressed!

Knowing the gifts of others in your church/ministry/team/etc can be very helpful, as you mentioned. It certainly makes it easier to show grace to each other when we know why people do the things they do or stress certain things that we may not . At the church I attend, they recognize people have certain areas they are suited for and areas they can "help" in, just to fill in the gaps until the right person comes along. They stress that the majority of what you do should fit your gift, but there is still room to help out in other areas. I like that--- I've been in places where they shove you in a spot, regardless of your gifts and talents. In the end, that's not good for anybody. 

As for praying to NOT have the gift of celibacy- hah! Priceless! I wonder if there are a lot of moms who want grandchildren some day who pray the same thing over their children..... ; )
