Music can affect us in many different ways. It often has a soothing effect (1 Samuel 16:23). As followers of Jesus Christ, we have our moments when we think about all the benefits we have in Christ, we cannot help but worship and sing praises to our Savior (Psalm 5:11).
King Solomon, in his great experiment that he documented in the book of Ecclesiastes, concluded that there is nothing new under the sun (Ecclesiastes 1:9). But in Christ Jesus, there is newness (Revelation 21:5). One of the things He made new is the song He put in our hearts and minds (Psalm 33:3; Psalm 40:3; Isaiah 42:10; Revelation 5:9).
The new song puts joy in our hearts and on our lips, so much so that we must express it openly (Psalm 35:27; Psalm 47:1).
Sometimes this newness gives us a joy so profound that we have no way to express it other than being silent and worshipping our great God. The Apostle Peter said it best in his first letter (1 Peter 1:8) "...joy that is inexpressible and filled with glory."
God is AWESOME!
