Therefore, if anyone is in Christ, he is a new creation; old things have passed way, behold, all things have become new." 2 Corinthian 5:17

Scripture refers to new creations, born again believers, by different titles. Let's look at some of them.

Children/sons of God:
"But as many as received Him, to them He gave the right to become children of God, to those who believe in His name." John 1:12

"Blessed are the peacemakers, for they shall be called sons of God."
Matthew 5:9

"For as many as are led by the Spirit of God, these are sons of God."
Romans 8:14

"The Spirit bears witness with our spirit that we are children of God."
Romans 8:16

"Therefore you are no longer a slave but a son, and if a son, then an heir of God through Christ." Galatians 4:7

"For you are all sons of God through faith in Christ Jesus." Galatians 4:26

"Do all things without murmuring and disputing, that you may become blameless and harmless, children of God without fault in the midst of a crooked and perverse generation, among whom you shine as light in the  world." Philippians 2:14-15

Heirs of God:
"The Spirit Himself bears witness with our spirit that we are children of God, and if children, then heirs--heirs of God and joint heirs with Christ, if indeed we suffer with Him, that we may also be glorified together."
Romans 8:16-17

"And if you are Christ's, then you are Abraham's seed, and heirs according to the promise." Galatians 2:29

"Are they (the angels), not all ministering spirits sent forth to minister for those who will inherit salvation?" Hebrews 1:14

"Thus God, determining to show more abundantly to the heirs of promise the immutability (unchangeableness of His purpose) of His counsel, confirmed it by an oath." Hebrews 6:17 My parenthesis.
(Read verse 13-20 concerning the promise made to Abraham. We are included in that promise! See Genesis 12:1-3)

Sons of light:
Jesus speaking in John 12:35-36,
"Then Jesus said to them, 'A little while longer the light is with you. Walk while you have the light lest darkness overtake you; he who walks in darkness does not know where he is going. While you have the light, believe in the light, that you may become sons of light'..."
Remember Jesus said in John 9:5,
"As long as I am in the world, I am the light of the world."

And because the Believer is in Christ and He in the Believer, the light is still in the world! For He says in Matthew 5:14, "You are the light of the world..."
"Let your light so shine before men, that they may see your good works and glorify your Father in heaven." Vs. 16

The Apostle Paul tells us in Ephesians 5:8, "For you were once darkness, but now you are light in the Lord. Walk as children of light."

Children of the Most High, the Holy Mighty God! And heirs with Christ!
How awesome! It is beyond our comprehension to understand, but with grateful hearts we bow down, worship and honor Him. Amen
