prayer and worship always strengthens my relationship with God. i feel closest to him during those times and i carry him with me after wards. if you take time out to just worship and pray with him you'll feel stronger.
but you have to make sure you're doing to consistently. not just like twice a week. every day (which is hard at first but you'll get used to it) your relationship will grow. but make sure you're reading your bible too and learning more about him. ^_^
