I have fought the good fight, I have finished the race, I have kept the faith. From now on there is reserved for me the crown of righteousness, which the Lord, the righteous judge, will give me on that day, and not only to me but also to all who have longed for his appearing.
We ourselves are Jews by birth and not Gentile sinners; yet we know that a person is justified not by the works of the law but through faith in Jesus Christ. And we have come to believe in Christ Jesus, so that we might be justified by faith in Christ, and not by doing the works of the law, because no one will be justified by the works of the law.
By faith he received power of procreation, even though he was too old—and Sarah herself was barren—because he considered him faithful who had promised.
Examine yourselves to see whether you are living in the faith. Test yourselves. Do you not realize that Jesus Christ is in you?—unless, indeed, you fail to meet the test!
For by grace you have been saved through faith, and this is not your own doing; it is the gift of God— not the result of works, so that no one may boast.
