Not a child anymore

something i read on the train on the way home really stood out to me. It's something that has been on my mind after a discussion on sunday. Something i need to reflect upon and to really think hard about. But here's the verse..

When I was a child, I talked like a child, I thought like a child, I reasoned like a child. When I became a man, I put the ways of childhood behind me. 1 Corinthians 13:11
