Psalm 134:1-2 (NIV)
Praise the Lord, all you servants of the Lord who minister by night in the house of the Lord. Lift up your hands in the sanctuary and praise the Lord.
I must admit, I feel a little timid when I worry about whether I should raise my hands in praise to God while worshiping. IA only happens when I see a few others doing so. My church is not given to such. Reading this verse, I am convicted to be only concerned with my personal worship and desire to magnify the Lord. I know that closing your eyes helps somewhat to get your focus off others and on God. On the other hand corporate worship ought to be just that, a body of worshipers acting in concert. Regardless, I should not feel any hesitation worshipping my Lord.
Luke 9:26 (NKJV)
For whoever is ashamed of Me and My words, of him the Son of Man will be ashamed when He comes in His own glory, and in His Father's, and of the holy angels.
