Adam's Physical D N A was Perfect because his Spiritual D N A was Perfect.   

Original Sin resulted in the corruption of Adam's Spiritual D N A.   Since his Physical D N A was a product of his Spiritual D N A, it became corrupted as well.   

The result of the corrupted Spiritual D N A which corrupted the Physical D N A is that Sickness and Death became a reality for mankind.   

Jesus answered, Truly, truly, I say unto you, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God. - Joh 3:5 The Sin Nature must be destroyed and replaced with a New Spirit which exists in the Kingdom Of God.      The Kingdom Of God is Heaven, the Spirit Realm, which is a dimension of existence higher than that of the space-time continuum in which all physical life exists.      It is not possible for the purely physical to exist in the Spirit Realm.     This is why we must be born of the Spirit.

In the New Birth we receive New Spiritual D N A which has the Gift of Eternal Life in it.   

Who his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes you were healed. - 1Pe 2:24 Jesus' Perfect Finished Work has made us the Righteousness of God.     His broken and beaten body has Healed us.

Beloved, I wish above all things that you may prosper and be in health, even as your soul prospers. - 3Jn 1:2 Is this just John's wish or is it the Father's also?     If just John's then he is wishing something against the Will Of God.     No, this is from God who Loves us and has given us the keys of the Kingdom and made us joint Heirs with Jesus Christ.

Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life. - Rom 6:4 The Sin Nature which we were born with is a result of Original Sin (Gen 2:17 Gen 3:10,11).      It was crucified with Christ.      By Faith in Christ Jesus we are Born Again - made New Spirit beings (Joh 3:5 Gal 5:25).      Your mind, emotions and body were not crucified with Christ.     You must crucify them by acts of your will.      → let this mind be in you - Phi 2:5 → mortify your members - Col m:5 → submit yourselves to God - Jam 4:7 → resist the devil - Jam 4:7 → present your body - Rom 12:1 → follow peace with all men - Heb 12:14 → have Faith in God - Mar 11:22 and so on.      All the action verbs above indicate that our soul (mind and emotions) are not instantly perfected in the New Birth as our spirit is (1Co 2:6 Phi 3:15).      This verse says that we have Newness Of Life but we must walk in it.     Walk is an action verb implying that we have to knowingly and wilfully decide to let the New Spirit being manifest.      Otherwise, it won't.      Spirit Salvation is instantaneous.      Soul Salvation is a process totally dependent on our will while we are in the flesh.      At His return Jesus will finish His redemption work by translating us from corruptible to incorruptible (1Co 15:50-55).      In the meantime, our Lord expects us to press toward the mark (Phi 3:14).

So, we see that Christ Jesus made it possible for us to be Born Again and so Receive Eternal Life and Abundant Life.   

But my God shall supply all your need according to his riches in glory by Christ Jesus. - Phi 4:19 I think Paul's use of the phrase 'my God' indicates two things: 1) that he knew God personally, 2) that others had a misconception of God.      Paul received personal Revelation of the Gospel by the Holy Spirit so that he had no doubts about the finished work of Christ Jesus, the boundless Love that it demonstrated and the amazing Grace that it provided.      Unfortunately, Humanity has a long history of perceiving god as mean-spirited and vindictive.     So, he was basically saying that if your god does not supply all your needs then you may be worshipping another god or at least Ignorant of the True and Living God.      The riches of my God are immeasurable, as is His Love, as is His Grace and all that is needed to appropriate those riches is Faith in His Goodness and His Word.

That you may walk honestly toward them that are without, and that you may have lack of nothing. - 1Th 4:12 Honesy and integrity are the products of attention to study and work.      The implication is that those who do not study the Word and who do not work with their hands, will end up being deceitful and impoverished.
