Rom 8:1 1There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit. There is absolutely no way one can be condemned by God, who is in Christ Jesus, and who walks not after the flesh [unregenerated] but after the Spirit [regenerated]. The first part of this verse needs some clarification, before we can rightly understand the second part " who walk not after the flesh, but after the Spirit" When exactly is the believer ever in Christ Jesus ? How did they get into Christ Jesus in the first place ? To answer the first question, the believer, before they believed or before they were physically born into this world, were in Christ Jesus before the World began. 2 Tim 1:9 9Who hath saved us, and called us with an holy calling, not according to our works, but according to his own purpose and grace, which was given us in Christ Jesus before the world began, So the believer, before the world began was in Christ Jesus representatively in the Covenant of Grace, before the world began. Thats why it is stated that Grace was given them in Christ Jesus at that early date, how else can we understand " Grace which was given us" It was given to their Head and Representative of the Seed, His Seed Chosen in Him before the foundation Eph 1:4 4According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love: The Chosen seed ! Isa 41:8 But thou, Israel, art my servant, Jacob whom I have chosen, the seed of Abraham my friend. The Chosen generation which means seed or the Chosen seed 1 Pet 2:9 But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light; Now secondly, How did they get into Christ Jesus in the first place ? By God the Fathers good pleasure 1 Cor 1:29-30 29That no flesh should glory in his presence. 30But of him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption: That no flesh can boast of themselves being the cause of their being in Christ, Paul says it's of God [Father] that ye are in Christ Jesus, and He was made all those things unto them as He was made their Covenant Head and Surety, He is made unto them wisdom, and righteousness,and sanctification and redemption [of the body in the future]. So to these, even before they believed were in Christ, and therefore they were never under Condemnation, even as being born sinners and dead in trespasses and sins.
