Romans 4:23-25
In these three verses, Paul, for the first time, links Jesus' resurrection to salvation.  He has written convincingly in the first three chapters of Romans of our guilt, our trespasses and our need to be made right with God.  Man's desperate condition necessitates salvation from God's just wrath.  

In Romans 1:16-17, Paul describes the Gospel as the power of God for salvation because the righteousness of God through faith is made known through His Good News.  Paul then, in an overwhelming fashion, describes man's unrighteousness which deserves God's righteous judgment.  In Romans 2-3, he drives home the point that all mankind needs to be made right with God, not just Gentiles, those without the Law, but Jews also.  Romans 3 explains God's salvation is available not through man's work but through Jesus' work, who is the propitiation God provided through His grace.  Chapter four examines how Abraham, the father of all who are justified before God, is declared righteous. It is not through circumcision (his work) but through faith so that God's grace will be displayed.  God records the history of Abraham being counted righteous so we, too, would know the only way to be right with Him is through His Son, who He put forward as the propitiation by His blood.  

So how does God prove His acceptance of Jesus, who was delivered up for our trespasses?  How can we know God's just wrath is propitiated or appeased?  HE IS ALIVE!!  Death could not hold Him!  The penalty for sin is death, but since Jesus was sinless, death had no power over Him.  Jesus' resurrection is the demonstration of His innocence.   God's Gospel, His power of salvation requires both Jesus being delivered up for our trespasses and being raised up for our justification.  

I have previously used prayers from Valley of Vision.  This Puritan prayer is appropriate.

Great was the joy of Israel's sons, when Egypt died upon the shore, Far greater the joy when the Redeemer's foe lay crushed in the dust.

Jesus strides forth as the victor, conqueror of death, hell and all opposing might;
He burst the bands of death, tramples the powers of darkness down and lives forever.

He, my gracious surety, apprehended for payment of my debt, comes forth from the prison house of the grave free and triumphant over sin, Satan, and death.

Show me herein the proof that his victorious offering is accepted, that the claims of justice are satisfied, that the devil's scepter is shivered, that his wrongful throne is leveled.

Give me the assurance that in Christ I died, in him I rose, in his life I live, in his victory I triumph, in his ascension I shall be glorified.

Adorable Redeemer, thou who wast lifted up upon a cross art ascended to highest heaven.  Thou, who as a Man of sorrows wast crowned with thorns, art now as Lord of life wreathed with glory.  

Once, no shame more deep than thine, no agony more bitter, no death more cruel.  Now, no exaltation more high, no life more glorious, no advocate more effective.  Thou art in the triumph car leading captive thine enemies behind thee.

What more could be done than thou has done!  
Thy death is my life,
thy resurrection my peace,
thy ascension my hope,
thy prayers my comfort.
