Read The Remedy for Paralyzed Sinners and Fallen Saints, by John Piper of Desiring God, at One Place.
"God did his most deadly work to destroy hopelessness and futility and provincial cowardice. He gave up his Son to torture and death. A perfect life, a perfect death, and the decisive work was done.
"But there are millions who are numb to hope because of the God-belittling things they have done and how ugly they have become. They don't lift lofty arguments against God's Truth; they shrug and feel irretrievably outside. They don't defy God consciously; they default to cake and television. Except for the periodic rush of sex and sport and cinema, life yawns. There is no passion for significance. For many, no passion at all.
"There is a Christian version of this paralysis. The decision has been made to trust Christ. The shoot of hope and joy has sprung up. The long battle against sin has begun. But the defeats are many, and the plant begins to wither. One sees only clouds and gathering darkness. The problem is not perplexing doctrine or evolutionary assaults or threats of persecution. The problem is falling down too many times. Gradually the fatal feeling creeps in: the fight is futile; it isn't worth it."
For if, by the trespass of the one man, death reigned through that one man, how much more will those who receive God's abundant provision of grace and of the gift of righteousness reign in life through the one man, Jesus Christ. Consequently, just as the result of one trespass was condemnation for all men, so also the result of one act of righteousness was justification that brings life for all men. For just as through the disobedience of the one man the many were made sinners, so also through the obedience of the one man the many will be made righteous.
But to the one who does not work, but believes in Him who justifies the ungodly, his faith is credited as righteousness
For we maintain that a man is justified by faith apart from works of the Law.
For Christ is the end of the law for righteousness to everyone who believes.
He made Him who knew no sin to be sin on our behalf, so that we might become the righteousness of God in Him.
2 Corinthians 5:21
Do not rejoice over me, O my enemy. Though I fall I will rise; Though I dwell in darkness, the LORD is a light for me. I will bear the indignation of the LORD Because I have sinned against Him, Until He pleads my case and executes justice for me. He will bring me out to the light, And I will see His righteousness.
For if by the transgression of the one, death reigned through the one, much more those who receive the abundance of grace and of the gift of righteousness will reign in life through the One, Jesus Christ. So then as through one transgression there resulted condemnation to all men, even so through one act of righteousness there resulted justification of life to all men. For as through the one man's disobedience the many were made sinners, even so through the obedience of the One the many will be made righteous.
