Brothers and sisters, my heart’s desire and prayer to God for the ISRAELITES is that they may be saved.
For I can testify about them that they are zealous for God, but their zeal is not based on knowledge. Since they did not know the righteousness of God and sought to establish their own, they did not submit to God’s righteousness. Christ is the culmination of the law so that there may be righteousness for everyone who believes.
Moses writes this about the righteousness that is by the law: “The person who does these things will live by them.” But the righteousness that is by faith says: “Do not say in your heart, ‘Who will ascend into heaven?’” (that is, to bring Christ down) “or ‘Who will descend into the deep?’” (that is, to bring Christ up from the dead).
But what does it say? “The word is near you; it is in your mouth and in your heart,” that is, the message concerning faith that we proclaim: If you declare with your mouth, “Jesus is Lord,” and believe in your heart that God raised him from the dead, you will be saved. For it is with your heart that you believe and are justified, and it is with your mouth that you profess your faith and are saved.
As Scripture says, “Anyone who believes in him will never be put to shame.” For there is no difference between Jew and Gentile—the same Lord is Lord of all and richly blesses all who call on him,
Therefore God exalted him to the highest place
and gave him the name that is above every name,
that at the name of Jesus every knee should bow,
in heaven and on earth and under the earth,
and every tongue acknowledge that Jesus Christ is Lord,
to the glory of God the Father.
By myself I have sworn;
from my mouth has gone out in righteousness
a word that shall not return:
To me every knee shall bow,
every tongue shall swear allegiance.’
“Only in the Lord, it shall be said of me,
are righteousness and strength;
to him shall come and be ashamed
all who were incensed against him.
In the Lord all the offspring of Israel
shall be justified and shall glory.”
1 Corinthians 1:30
And because of him you are in Christ Jesus, who became to us wisdom from God, righteousness and sanctification and redemption,
Please look at this for my understanding of being born again. The born again humanity. | His Grace Is Enough
