What the Holy Bible says about being a New Creation:
17 Therefore, if anyone is in Christ, the new creation has come: The old has gone, the new is here! (2 Corinthians 5: 17)
22 You were taught, with regard to your former way of life, to put off your old self, which is being corrupted by its deceitful desires; 23 to be made new in the attitude of your minds; 24 and to put on the new self, created to be like God in true righteousness and holiness. (Ephesians 4: 22-24)
8 For you were once darkness, but now you are light in the Lord. Live as children of light 9 (for the fruit of the light consists in all goodness, righteousness and truth) 10 and find out what pleases the Lord. 11 Have nothing to do with the fruitless deeds of darkness, but rather expose them. 12 It is shameful even to mention what the disobedient do in secret. 13 But everything exposed by the light becomes visible—and everything that is illuminated becomes a light. 14 This is why it is said: “Wake up, sleeper, rise from the dead, and Christ will shine on you.” (Ephesians 5: 8-14)
15 Be very careful, then, how you live—not as unwise but as wise, 16 making the most of every opportunity, because the days are evil. 17 Therefore do not be foolish, but understand what the Lord’s will is. 18 Do not get drunk on wine, which leads to debauchery. Instead, be filled with the Spirit, 19 speaking to one another with psalms, hymns, and songs from the Spirit. Sing and make music from your heart to the Lord, 20 always giving thanks to God the Father for everything, in the name of our Lord Jesus Christ. (Ephesians 5: 15-19)
