There are several Psalms that encourage us to sing to the Lord.  No matter what our condition or circumstance is, we should sing to the Lord.  The Lord is our salvation so we should sing joyfully.  The Lord’s Glory is upon us so we should sing a new song that declare His wondrous works.  The Lord Reigns so we should sing a song of love for all that He does.  We should make a joyful noise unto the Lord in gladness.  There is nothing that we experience nor endure that the Lord is not there with His Mercy and His justice.  So, sing a song to the Lord with the way we live our life, that never ends proclaiming our hope, faith, and trust in Him.
