Psalm 144:9 I will sing a new song unto thee O God: upon the psaltery and an instrument of ten strings will I sing praises unto thee.
Our Lord, as a warrior, fights for us and delivers us from evil. He gives salvation by grace for Christ’s sake. Therefore, as a thankful response we will sing praises to the Lord, and part of that praise will be the singing of a new song. Of course, new songs of praise are not new to Him, for He originates the song in our hearts and it comes back to Him in worship, thanks and praise. But every time we sing to the Lord it is new and fresh for us, even when we sing an old song. It is new because God’s mercies are new every morning. We awake with a new song in our hearts and are refreshed each new day.
At times we use, or at least imagine, musical instruments to accompany our songs of praise every day. We may sing off key and out of tune, but we “make a joyful unto the Lord,” for He is good every day, He delivered us, and His power and love remain with us always. This new song may be in our thoughts, whispered, or sung out loud; it may be by us alone in private or it may be with others; but our Savior and Shepherd is eternally present with us.
