Merton most succinctly identifies what he means by vocation in his book No Man Is an Island, in which we read, Each one of us has some kind of vocation. We are all called by God to share in His life and in His kingdom. Each one of us is called to a special place in the Kingdom. If we find that place we will be happy. If we do not find it, we can never be completely happy. For each one of us, there is only one thing necessary: to fulfill our own destiny, according to God’s will, to be what God wants us to be.
