Let's talk about Christian Life in Christ:
"I have been crucified with Christ and I no longer live, but Christ lives in me. The life I now live in the body, I live by faith in the Son of God, who loved me and gave himself for me." - Gal 2:20
The Scriptures teach that the Logos (Jesus) is everlasting life, having life in Himself, and the source of life, physical, intellectual, and spiritual. They further teach that his incarnation was the necessary condition of the communication of spiritual life to the children of men. He, therefore, is the only Saviour, the only source of life to us. We become partakers of this life, by union with Him. This union is partly established in the councils of eternity; partly vital by the indwelling of the Holy Spirit; and partly voluntary and conscious by faith. It is to those who believe, to those who receive Him as manifested in the flesh, that He becomes eternal life (1Jo 4:2). For it is not they who live, but Christ who liveth in them (Gal 2:20). The life of the believer is not a corporate life, conditioned on union with any outward organization, called the Church, for whosoever calls on the name of the Lord, that is, whosoever religiously worships Him and looks to Him as his God and Saviour, shall be saved, whether in a dungeon or alone in a desert.
