People like the idea of self-made fortunes, but that is not really based in reality. In the end everyone needs support, encouragement and help from someone. This is also true for our lives of faith. There are no self-made Christians. All the followers of Jesus have been given the gift of faith as it comes to them passed from one generation to the next.
This is actually a great strength of the faith because it grounds us in relationships; with one another and with God.
