Psalms 98:1

Psalms 98:1 says, A Psalm  This simply says it is a psalm, then verse one says, O sing unto the LORD a new song; for he hath done marvellous things: his right hand, and his holy arm, hath gotten him the victory.  The people of Israel were called on to sing a new song to God because of the marvelous things He had done.  This psalm is a prophesy of the coming Messiah, and His coming is the marvelous thing that God has done that means the most.  Verse two adds, The LORD hath made known his salvation: his righteousness hath he openly shewed in the sight of the heathen.  When Jesus came, He made known the salvation plan of God and showed God's righteousness openly to the heathen, which everyone is until they accept Him as their Savior and Lord.  Verse three continues, He hath remembered his mercy and his truth toward the house of Israel: all the ends of the earth have seen the salvation of our God.  Though God made His covenant with the people of Israel, it was to call all people to Him through faith.  As Christians, we have entered into a covenant relationship with God that separates in us from the rest of the world, but part of that covenant relationship calls on us to witness to the lost people of the world.  Verse four states, Make a joyful noise unto the LORD, all the earth: make a loud noise, and rejoice, and sing praise.  The whole world is called on to make a joyful noise unto the LORD and to rejoice and sing loudly to Him.  Verse five adds, Sing unto the LORD with the harp; with the harp, and the voice of a psalm.  People are called on to play music and sing to the LORD.  Verse six adds, With trumpets and sound of cornet make a joyful noise before the LORD, the King.  This just continues to tell the people that they are to worship God using musical instruments, and this still applies to the church today.  Verse seven declares, Let the sea roar, and the fulness thereof; the world, and they that dwell therein,  There is the beginning of a call for all of  God's creation to call out to Him, from the seas and hills to all the animals that live in them.  Verse eight adds, Let the floods clap their hands: let the hills be joyful together.  Though mankind is the only part of creation with an everlasting soul, when God is truly in charge, all of creation works together for our good.  Verse nine continues, Before the LORD; for he cometh to judge the earth: with righteousness shall he judge the world, and the people with equity.  God is one day coming in righteousness judgment, and the only way that we can be declared righteous is by faith in Jesus Christ.
