Praise ye the LORD. Sing unto the LORD a new song, and his praise in the congregation of saints.
Sing unto the LORD a new song, or a song that is fresh and renewed. The word new here in Psalm 149:1 is a word that is also used to describe polishing and cleaning or renewing a sword.
When Moses and the children of Israel had come up out of the Red Sea and after the enemy had been drowned in the sea behind them, Israel sang a new song. Exodus 15:1, “Then sang Moses and the children of Israel this song unto the LORD, and spake, saying, I will sing unto the LORD, for he hath triumphed gloriously: the horse and his rider hath he thrown into the sea.” We are commanded in Psalm 149 to sing a new song.
So often in life we frail human beings allow ourselves to be pushed down into defeat singing the same old tired and worn out song of defeat over and over. When we find ourselves in trying, difficult circumstances and situations that is exactly the time to dust off and polish up our praise to the LORD and sing a new song unto Him that made us and is our King. Even when we feel like doing anything except singing we can look back on what the LORD brought us through yesterday and then sing in confident faith and steadfast trust knowing that He will get the victory and bring us through the current difficulties as well.
Singing a new song unto the LORD can be likened unto polishing a sword. So when I sing a new song unto the LORD that is exactly the instrument that gets me the victory over the defeat that seems so imminent in my current circumstance.
Hebrews 13:8, “Jesus Christ the same yesterday, and to day, and for ever.” The Lord brought us through yesterday and He is the same LORD today that He was yesterday and it is a surety that He will bring us through the present difficulties. Polish up your song of praise and thanksgiving and go to battle defending the goodness, mercy and compassion of Jesus Christ in your present circumstances and the victory shall be yours.
