The fear of the LORD is the true basis for living the Christian life where the rubber meets the road and in a way that pleases God. That, I believe, is how we are -filled- with the Spirit and empowered to live a life that brings Him much glory. It is not some ethereal, mystical -infilling- that we are to look for, but a real understanding and growth of the fear of the LORD that transforms us from within-so that our lives become more naturally filled with His character and likeness. Because the changes come from-within-us, living the Christian life becomes far more natural to us.
