“Therefore if anyone is in Christ, he is a new creature; the old things passed away; behold, new things have come.”
2 Corinthians 5:17 NASB
When you accept Jesus as your personal Lord and Savior you are considered "in Christ". So every time you see this phrase in the scripture you can apply it to yourself. These scripture will paint a picture for you of what you already have now that you are "in Christ".
