We are currently memorizing this Psalm. Due to the fact that this passage uses so few words to proclaim so much truth, I color-coded it for easier reference.
A Psalm.
1Oh sing to the LORD a new song, for he has done marvelous things! His right hand and His holy arm have worked salvation for Him.
2The LORD has made known His salvation; He has revealed His righteousness in the sight of the nations.
3 He has remembered His steadfast love and faithfulness to the house of Israel. All the ends of the earth have seen the salvation of our God.
4 Make a joyful noise to the LORD, all the earth; break forth into joyous song and sing praises!
Psalm 98:1-4 (ESV*)
*****************************************************************************************************************
And He saw that there was no man, and wondered that there was no intercessor: therefore His arm brought salvation unto Him; and His righteousness, it sustained Him. Isaiah 59:16 (KJV*)
The LORD hath sworn by His right hand, and by the arm of His strength, Surely I will no more give thy corn to be meat for thine enemies; and the sons of the stranger shall not drink thy wine, for the which thou hast laboured:
But they that have gathered it shall eat it, and praise the LORD; and they that have brought it together shall drink it in the courts of My holiness.
Go through, go through the gates; prepare ye the way of the people; cast up, cast up the highway; gather out the stones; lift up a standard for the people.
Behold, the LORD hath proclaimed unto the end of the world, Say ye to the daughter of Zion, Behold, thy salvation cometh; behold, His reward is with Him, and His work before Him.
And they shall call them, The holy people, The redeemed of the LORD: and thou shalt be called, Sought out, A city not forsaken. Isaiah 62:8-12 (KJV*)
But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets;
Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference:
For all have sinned, and come short of the glory of God;
Being justified freely by His grace through the redemption that is in Christ Jesus:
Whom God hath set forth to be a propitiation through faith in His blood, to declare His righteousness for the remission of sins that are past, through the forbearance of God;
To declare, I say, at this time His righteousness: that He might be just, and the justifier of him which believeth in Jesus.
Romans 3:21 (KJV*)
When you read this, you can perceive my insight into the mystery of Christ,
which was not made known to the sons of men in other generations as it has now been revealed to His holy apostles and prophets by the Spirit.
This mystery is that the Gentiles are fellow heirs, members of the same body, and partakers of the promise in Christ Jesus through the gospel. Ephesians 3:4-6 (ESV*)
As Paul wrote to the Romans, we all need to be rescued from the death to which humanity has been subjected.
Salvation is the work of God alone.
He keeps His promises.
He has thrown open the offer to Jews and gentiles (nations) alike. And He desires for all to be saved and come to knowledge of His Truth (1 Timothy 2:4-6)
We now have access to our Maker through faith in the atoning life, death and triumph of our Lord Jesus Christ!
This is stunningly Good News!!!
