2 Corinthians 5:17, 21 KJV

17. Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.

21. For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.

Many people don't know the value of Christianity (they don't take it serious). Despite the teachings and preaching yet we found people living a life that's unpleasant.

A new creation was born after the birth of Christ. An old man in sin has no Life Of God. There is no creation in the whole world that possess the nature of the Most High God. It's only the born again Christian that has the nature of God, the Spirit of God, and the Life Of God.
When the Holy Ghost came to renew us, we have the Nature Of God and the Glory Of God.
There are number of things that differentiate us from the old creation. As a new creation, you are a billion miles away from the old creation. You are seated together with Christ and the earth has become a footstool. If you don't believe this, you will not enjoy it. You have to believe the new creation.

The destiny of an old man is eternal death (Romans 6:23a).
So he or she have to come to God in sincerity and repent of his or her sins because "the soul that sinneth, it shall die" (Ezekiel 18:20).
"For all have sinned, and come short of the glory of God" (Romans 3:23).

So as a new creation, God of heaven is sending you to those that does not know Him to lead them to know Him. The God of heavens would release that grace that came upon you the day you encountered Him on them also to have the experience.

God has granted the 'new creation' the highest honour by bringing them into the fellowship with Him. And a new creation do not live a substandard life.
A substandard life will show how you reason, talk, dress, behave as a Christian.

Be a new creation and a partaker of divine blessing. Amen...!!!
