Vent away

May I please vent a little and make a few suggestions about our Presbyterian denomination.
Wouldn't it be great if we could have more openness with the Lord in worship and praise — music-wise, of course; more freedom of physical expression: Praise you, Amen; God loves us; He is our daily Saviour.
Why can't we express our love and worship without feeling embarrassed? If God comes through others, why not let God come through me? I believe we should not grieve the Holy Spirit, but let him shine with our expressions of worship and love. I believe the Presbyterian church would be opening its doors to many lost souls who want to be saved.
The Lord understands our hearts and spirituality. We also should try to be more robust in worshipping our Lord.
