"Sing unto the Lord, bless His name; shew forth His salvation from day to day." (Psalm 96:2)
"Enter into His gates with thanksgiving, and into His courts with praise: be thankful unto Him, and bless His name." (Psalm 100:4)
"I will extol thee, my God, O king; and I will bless thy name forever and ever... My mouth shall speak the praise of the Lord: and let all flesh bless His holy name forever and ever." (Psalm 145:1, 21)
"O bless our God, ye people, and make the voice of His praise to be heard." (Psalm 66:8)
When we "literally" bow our knees before God in praise to worship Him, we give Him permission to do a miracle in our lives. We are blessed, as we bless God and praise Him.
It is while we are on our knees, that we physically offer ourselves to Him. We offer our bodies with all of our heart, mind, soul and strength. It is in this way that we show our love towards Him and that he is our Lord, God and King.
"Love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength. There is no commandment greater..." (Mark 12:29-31)
