Psalm96:1-3 O sing unto the Lord a new song, sing unto the Lord, all the earth. Sing unto the Lord, bless his name, shew forth his salvation from day to day. Declare his glory among the heathen, his wonders among all people.
Because “the Lord is great, and greatly to be praised, and believed above all,” we respond with singing, blessing and telling. Every time, every day, we sing a new song, not necessarily new to us nor new to God, but it is from a heart that has been refreshed and made new by the working of the Holy Spirit through the Gospel. Singing is to the Lord, not a performance to others. Although we feel better, it is not to make us feel good. Instead, singing blesses the Lord and makes Him feel better, as if He needed it. So we sing praises in the congregation of believers weekly and in private day by day, “making melody in our hearts to the Lord.”
In addition, we tell His salvation daily in our living, we declare His glory among a godless generation, and we support the preaching of the wonderful gospel to all people. The Good News is so wonderful we cannot help but pray for others to know the same great salvation.
