For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live. Rom.8:13... Paul emphasizes the necessity for continual warefare against all that would limit the work of God in our lives. Rom.6:11-19, for sin is always striving to regain control over us. This spiritual conflict although directed against Satan and evil spiritual forces. Eph.6:12 is primarily against the passions and desires of the flesh, thats is sinful human nature. Gal.5:16-21; Jas.4:1; 1 Pet.2:11. we as believers must continually decide whether we will surrender to the inclinations of sinful human nature or to the demands of the divine nature of which we partake. Gal.5:16,18; 2 Pet.1:4. The results of failing to put to death the sinful deeds of the body is spiritual death. Rom.8:6,13 and the loss of inheritance in the kingdom of God. Gal.5:19-21. the words ye shall die mean that a Christian can pass from spiritual life back into spiritual death. Thus the life that we receive at our new birth. John 3:3-6 can be extinguished in the soul of the believer who refuses to put to death by the Spirit the sinful deeds of the body. Paul gives the basis for the as*urance of salvation here in Rom.8:13,14. If one is consistently putting to death the sinful deeds of the body, then we are being lead by the Spirit. Those lead by the Spirit are sons of God. Amen Hallelujah
