Sometimes people get turned off "God" because they confuse institutional Christianity with a relationship with a Higher Power.
Although many people find God through Jesus Christ, Christianity is not the only path to God.
Simple daily contemplative practices can bring you closer to your Higher Power. Just 5 minutes of quiet prayer or meditation every morning before you start your day can make a huge difference in your life - I say this from experience.
The works of Wayne Dyer are very spiritual and also very practical. I recommend The Power of Intention - Learning to Co-create Your World Your Way by Dr. Wayne W Dyer.
