2Cor.5:17(Amp) says, "Therefore, if any person is ingrafted in Christ Jesus (the Messiah), he is a new creation (a new creature altogether); the old previous moral and Spiritual condition has passed away. Behold, the fresh and new HAS COME."
We can only discover who God created this new creation man/woman to be, through Revelation of God's Word. Natural man cannot show us who we've become, because this Revelation is Spiritually discerned. 1Cor.2:13(Amp) says, "And we are setting these Truths forth in Words not taught by human wisdom but taught by the Holy Spirit, combining and interpreting Spiritual Truths with Spiritual language to those who possess the Holy Spirit."
A carnal mind can't discern the Truth of the new creation being. We must learn who we are now by God's Word and the Holy Spirit. Believers have been held in bondage by carnal thinking and rituals, some which say that "We will only become new creations after we die and go to Heaven." Carnal thinking has left God's Church impotent and useless to today's world. Those who came to the Lord with only man's ideas of the new birth, are still in bondage to carnal thinking and devoid of the Truth of what Jesus has done for us now.
We must go to the One Who created us, in order to find out who and what God has made us to be. 2Cor.3:17-18(Amp) says, "Now the Lord is the Spirit and where the Spirit of the Lord is, there is liberty (emancipation from bondage, freedom). And all of us, with unveiled face, because we continue to behold in the Word of God, as in a mirror the Glory of the Lord, are constantly being transfigured into His Very Own Image in ever increasing splendor and from one degree of Glory to another, for this comes from the Lord Who is Spirit."
James1:23-25(Amp) says, "For if anyone only listens to the Word without obeying it and being a doer of it, he is like a man who looks carefully at his own natural face in a mirror: for he thoughtfully observes himself, and then goes off and promptly forgets what he was like. But he who looks carefully into the faultless Law (the Law of Liberty), and is faithful to it and perseveres in looking into it, being not a heedless listener who forgets but an active doer who obeys, he shall be Blessed in his doing, his life of obedience."
God's Word is a mirror that reflects back to us, who we've now become through Jesus, as God's new creation family. God's Word is the Faultless Law of Liberty, which reflects who we are now in this new creation and not who we once were. Through Jesus, we've been created righteous, pure, holy, justified, and joint heirs with Him.
This is not what we've been taught over the years, which fosters mistrust in what God's Word says about the new creation beings. Religion has left us fearful of being full of pride, so we continue seeing ourselves as unworthy sinners and unrighteous in God's eyes. If God made us a new creation, then did He create us like we were when we came to Him? Or, did God create us in the image He intended us to be, as His family?
If God left us like we were, then we're not new creations, but we're left to be tolerated and not accepted by Him. God chose us to be His very Own children and created us to be exactly that, without spot or wrinkle, in Jesus. This is by God's choosing and not ours. Do we still make mistakes? Of course, but these mistakes grow smaller as we develop our new creation spirit, making it stronger and more mature in Him.
Our problem isn't that what Jesus did isn't enough, but that we have walked in the flesh and carnal mind, maintaining the habits from who we were before being born-again. We thought like the world, talked like the world, were raised by the world and we're now faced with an entirely new way of living and need to be taught anew by the Spirit. This is why Paul instructed in Rom.12:2(Amp), saying, "Do not be conformed to this world (age), fashioned after and adapted to it's external, superficial customs, but be transformed, changed by the entire renewal of your mind, by it's new ideals and it's new attitude, so that you may prove for yourselves what is the Good and acceptable and perfect will of God, even the thing which is Good and acceptable and perfect in His sight for you." What is Good, acceptable and perfect in His sight? The new creation man/woman who was created by His Own will for Himself, as His very Own children.
God doesn't find it pleasing and Good, when we deny what He has done in us, by Jesus. Heb.11:6(Amp) says, "But without faith it is impossible to please or be satisfactory to Him. For whoever would come near to God must necessarily believe that God exists and that He is the Rewarder of those who earnestly and diligently seek Him out." We can only cone near to God by right standing, not in our own right standing, but by faith in God's Free Gift of Righteousness. If we don't have faith in this Gift of Righteousness, then we won't come near Him in confidence.
We must develop our new creation man/woman, so we can come before God in confidence and with the assurance. We must have faith in what God has done for us in Jesus and by His Blood Sacrifice, making us new creatures altogether.
