It's all about where your faith is. "Without faith it is impossible to please God," and "The just shall live by faith." If you have the mentality that you're doing everything on your own, you're not approaching God with faith. If you get to a point where you're taking God for granted, you're also not approaching Him with faith. It takes always being mindful of an active relationship with God. I think that's probably a big part of what Paul was talking about when he said "pray without ceasing." Obviously we have responsibilities and we can't always just be stuffed away in a prayer closet praying. But we can at all times be mindful that God is within us, and invest in that active relationship with Him. There is also a balance of looking at God as our friend, lover, or "Papa" and not losing the fear, respect, and reverence for Him as God Almighty.
