Overcomers and Non-Overcomers in Christ

8. Are there both spiritual and fleshly 'carnal' Christians (Rom. 7.14,19; 1 Cor. 3.1)?

Do you believe there is the matured or spiritual Christian and the fleshly or carnal Christian (Rom. 7.14,19; 1 Cor. 3.1); and that the larger portion of all believers though all saved do not "overcometh" (Rev. 2.7,11,17,26; 3.5,12,26) in Christ before leaving their bodies of flesh and blood? "Make every effort to supplement your faith with virtue, and virtue with knowledge, and knowledge with self-control, and self-control with steadfastness, and steadfastness with godliness, and godliness with brotherly kindness, and brotherly kindness with love" (2 Pet. 1.5-7).
