Shout joyfully to the LORD, all the earth; Psalms 98:4
Singing a song of praise should always be our response when God delivers us from troubles and both during times of joy and sorrow. The Psalmist here is praising God for being so faithful in being a source of rescue. Praising God is something that we should be exercising and living in our hearts each and every day. The nation of Israel was constantly being challenged with learning to remember all that God had done for them and being grateful for all that He had done. He delivered them countless times from their enemies and forgave them each time they sinned against Him.
In the same way God has also delivered us from eternal punishment and death by dying on the cross and forgiving us of our sin. Let us always remember just how far Christ went to pay the ultimate act of deliverance and sacrifice. As the Psalmist praised “O sing to the LORD a new song, for he has done marvelous things” so we too should praise Him all the time.
