Why singing matters in praising God ?
And do not get drunk with wine, for that is debauchery, but be filled with the Spirit, addressing one another in psalms and hymns and spiritual songs, singing and making melody to the Lord with your heart…
Let the word of Christ dwell in you richly, teaching and admonishing one another in all wisdom, singing psalms and hymns and spiritual songs, with thankfulness in your hearts to God.
About midnight Paul and Silas were praying and singing hymns to God, and the prisoners were listening to them…
Singing and making melody to the Lord with our hearts is evidence of a Spirit-filled life.
Singing helps to imbibe the word of Christ in our hearts as it is easily memorized.
Singing praises to God corporately helps to build up one another as we are hearing confession of faith from one another. And also witness to the unbelievers when they realize how joyful we are in the Lord in our exuberant singing of praises and confession of faith.
Singing strengthens our faith in the midst of trials and suffering.
(Thanks be to God for giving me another ACRONYM to remember to sing praises exuberantly to Him every time.)
