I believe worship is personal even the style might differ ,
Psalm 50:23 says Whoso offerthpraise glorifieth me.Praise come in many forms and can come from any one.The rest of the verse says and to him that ordereth [his] conversation [aright] will I shew the salvation of God.This may be a shock but you don't have to be saved to Praise God or for him to honor it with his Presence.
