“‘Ye are the salt of the land, but if the salt may lose savour, in what shall it be salted? for nothing is it good henceforth, except to be cast without, and to be trodden down by men. ‘Ye are the light of the world, a city set upon a mount is not able to be hid; nor do they light a lamp, and put it under the measure, but on the lamp-stand, and it shineth to all those in the house; so let your light shine before men, that they may see your good works, and may glorify your Father who [is] in the heavens. ‘Do not suppose that I came to throw down the law or the prophets — I did not come to throw down, but to fulfil; for, verily I say to you, till that the heaven and the earth may pass away, one iota or one tittle may not pass away from the law, till that all may come to pass.”
Matthew 5:13-18 YLT98

“Having been declared righteous, then, by faith, we have peace toward God through our Lord Jesus Christ, through whom also we have the access by the faith into this grace in which we have stood, and we boast on the hope of the glory of God. And not only [so], but we also boast in the tribulations, knowing that the tribulation doth work endurance; and the endurance, experience; and the experience, hope; and the hope doth not make ashamed, because the love of God hath been poured forth in our hearts through the Holy Spirit that hath been given to us.”
Romans 5:1-5 YLT98
