Reverence is a form of worship.
Heb 12:28-29 says "Since we are receiving a kingdom that cannot be shaken, let us give thanks, by which we offer to God an acceptable worship with reverence and awe; for indeed our God is a consuming fire."
Reverence is treating someone or something with deep respect. We show deep respect for God because there is nothing greater than God.
When we reverence God He gives us so much in return, because it creates in us an openness for the Holy Spirit to help us.
