If you've never had an I-was-made-for-this moment, then I'm sorry for you. I had one on Monday and another one yesterday. I was doing ministry; I was being God's hands and voice to people. All I can say is that is what I was made to do. I can't give you the details of the ministry that I was doing, but the words I said came from God and I was used by him for his work.
Go ahead and argue with me about how God doesn't speak to us except through the Bible. The Bible says that the Holy Spirit will control us and gives us strength to do ministry and words to speak on God's behalf. There is nothing greater than being controled by the Spirit and getting to watch God do his thing.
I was made for this.
