...regardless of the cost.

I would say that neither manifestation, nor teaching transforms character. Charismatics flail at the dead horse of experience, evangelicals at teaching, but neither leads to transformation spiritually. The only thing that transforms us spiritually is the action of following Christ. You seek to follow, you fail and you learn. But in order to engage in following, you have to have a clear understanding of life in the kingdom of God; that you are accepted by the grace of God in Jesus and that lays the foundation for as much true doctrine as you can manage and as much manifestation of the Spirit as you can stand. Dallas Willard

Matthew 16:24-26
Then Jesus went to work on his disciples. "Anyone who intends to come with me has to let me lead. You're not in the driver's seat; I am. Don't run from suffering; embrace it. Follow me and I'll show you how. Self-help is no help at all. Self-sacrifice is the way, my way, to finding yourself, your true self. What kind of deal is it to get everything you want but lose yourself? What could you ever trade your soul for?
