God is everywhere. Not in a room or a certain church. He is everywhere! And His Spirit dwells in every believer!
It's not in a moment or a feeling you get at church. No where in the bible does it explain the experience with the Spirit as a 'tingly feeling.'
Many other religious people would affirm the same thing about their god if all we could say was "I feel His presence," or "I just know because I can feel it." Where is this in scripture? Where is the grounds for your faith then? Feelings are temperate! They come and go. And sometimes they are deceiving!
If you base your faith on emotions, you're sadly mistaken. Don't be mislead by your heart. Don't over-spiritualize every feeling or thought as a divine intervention with God. Read the scripture and pray to Him. That's where you'll 'connect' with the Lord. Jesus doesn't come and go. He is always there.
