Jeff,
""The carnal mind is enmity against God.""
The Mind of Christ is Oneness with God.
""Where does temptation find it's source?""
Jam 1:14 But every man is tempted, when he is drawn away of his own lust, and enticed.
Temtation is not sin yet.
James 1:15 Then when lust hath conceived, it bringeth forth sin: and sin, when it is finished, bringeth forth death.
We have the capacity to not sin. By the same James.
James 1:21 Wherefore lay apart all filthiness and superfluity of naughtiness, and receive with meekness the engrafted word, which is able to save your souls.
Who is the engrafted Word? 1Pe 1:23 Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever.
The word engrafted is better serviced by the word implanted in the context of the ability to save souls. It is the Mind of Christ implanted in the believer. It is the mind of Christ in the believer that is able to lay apart all filthiness and superfluity of naughtiness, by His commandment, "He who keeps my commandments" it is he that loves me. It is not sinning but keeping and loving, which in Him we have His capacity to do this, just like He did it with His Father.
Jhn 14:15 If ye love me, keep my commandments.
Jhn 14:21 He that hath my commandments, and keepeth them, he it is that loveth me: and he that loveth me shall be loved of my Father, and I will love him, and will manifest myself to him.
Jhn 15:10 If ye keep my commandments, ye shall abide in my love; even as I have kept my Father's commandments, and abide in his love.
Carnality is overcome by the mind not the flesh. That is what Paul is talking about. Do you have the MInd of Christ? Is Christ In You? Are you a new Creature in Christ? Is the Holy Spirit baptized into you by Christ? Is the Holy Spirit revealing Truth to you about the Christ in you? Are you baptized into Christ by God the Father and sealed by the Holy Spirit, not water baptism.
If your answers are yes, look what God has done at the Cross. None available before the Cross.
We are truly new Creatures in Christ Jesus.
2Cr 5:17 Therefore if any man [be] in Christ, [he is] a new creature: old things are passed away; behold, all things are become new.
Gal 6:15 For in Christ Jesus neither circumcision availeth any thing, nor uncircumcision, but a new creature.
In Christ: Phillip
