OP, please ignore the bizarre heretics above me. Let's lay our foundation with Jesus' words
>You search the Scriptures because you think that in them you have eternal life; and it is they that bear witness about me
Therefore since it is in scripture that we find eternal life through Jesus, let us see what they have to say of this
>For what does the Scripture say? “Abraham believed God, and it was counted to him as righteousness.” Now to the one who works, his wages are not counted as a gift but as his due. And to the one who does not work but believes in him who justifies the ungodly, his faith is counted as righteousness, just as David also speaks of the blessing of the one to whom God counts righteousness apart from works: "Blessed are those whose lawless deeds are forgiven, and whose sins are covered; blessed is the man against whom the Lord will not count his sin.”
What Paul is saying here is that the greatest blessing imaginable, that of having one's sins ignored by God (and therefore being able to stand in His presence) is given even to the most wicked of sinners not because they were sufficiently righteous to merit it but because of their faith alone. He continues and says
>For the promise to Abraham and his offspring that he would be heir of the world did not come through the law but through the righteousness of faith. For if it is the adherents of the law who are to be the heirs, faith is null and the promise is void. For the law brings wrath, but where there is no law there is no transgression.
For those who believe there is no wrath and no transgression, there is no mortal sin which can destroy the grace of justification; they will never fall into God's displeasure again no matter how much they sin because He no longer entreats with them as a judge with a criminal but a father with a son (in fulfillment of the prophecy "you shall no longer call me 'my lord' but shall call me 'my husband'"). And thus he ultimately concludes the passage
>Therefore, having been justified by faith, we have peace with God through our Lord Jesus Christ
