Spiritual weakness & deficiency comes from a lack of time spent with God. Our life always becomes a replica of how & where we spend our time. We must resist distractions & diversions.Jesus disciples were identified as those who had "been with Jesus".
If we don't make time for God, nothing we do in life, can be identified as coming from Him. Evaluate life regularly, if its not showing marks of Christ, spend less time where you've been, and spend more time in Gods presence.
