What does it mean to be a Christian?

Does it mean assenting to a particular belief-system? Does it mean consenting to a prescribed morality pattern? Does it mean changing and improving one’s behavior? Does it mean joining a church organization? Does it mean practicing regular rituals of worship?

Becoming a Christian is a spiritual reality that transpires in the spiritual core of our being. The most basic need of man is not physical rejuvenation, or psychological adjustment, or social improvement, but spiritual exchange and regeneration. Because all of mankind begin their physical lives spiritually “dead in their trespasses and sins” (Eph. 2:1,5), the primary need of man is to be made alive spiritually.

Man’s primary need is not more knowledge and education, nor is it self-realization and self-improvement. The need of man is to be “re-lifed” with the very life of God in the person of His Son, Jesus Christ. The Spirit of God gives life (II Cor. 3:6) to our spirit, causing our spirit to be alive (Rom. 8:10) with “newness of life” (Rom. 6:4). One who thus becomes a Christian “passes out of spiritual death into spiritual life” (I John 3:14).

The spiritual life that the Christian receives is the divine life of Jesus Christ. Jesus said, “I am the way, the truth, and the life” (John 14:6). “He who has the Son has the life; he who does not have the Son of God does not have the life” (I John 5:12). This “eternal life that is in Christ Jesus” (Rom. 6:23) is the spiritual life that Jesus came to bring (John 10:10) to restore man to God’s intent for humanity. Eternal life is not a commodity or state of existence that we receive after we die physically, but is the life of Jesus Christ in the Christian presently with an eternal continuum of perpetuity.

The singular reality that constitutes becoming a Christian is the presence of the Spirit of Christ in the spirit of an individual who receives Him by faith. “If anyone does not have the Spirit of Christ, he does not belong to Him” (Rom. 8:9), i.e. he is not a Christian!

This indwelling of the Spirit of Christ in the spirit of an individual is the life and presence of the Person and Being of the risen Lord Jesus. Paul encouraged the Corinthians to evaluate whether they were really Christians, by asking, “Do you recognize this about yourselves, that Jesus Christ is in you?” (II Cor. 13:5). The spiritual mystery of the gospel is “Christ in you, the hope of glory” (Col. 1:27); the basis on which Paul declares, “It is no longer I who lives, but Christ lives in me...” (Gal. 2:20).

When a person is “in Christ” and Christ is “in them,” they become a “new creature” (II Cor. 5:17), a “new man” (Eph. 4:24; Col. 3:10), raised to “newness of life” (Rom. 6:4) by the presence of Christ’s life in their spirit. They have a new spiritual identity as a “child of God” (Jn. 1:12; I Jn. 3:1,2,10), a Christ-one (one spiritually united with the living Christ), a Christian.
