Definition and Concept
True life, as understood within the Christian faith, refers to the abundant and eternal life that is found in a relationship with Jesus Christ. This concept is deeply rooted in the teachings of the Bible, where life is not merely biological existence but a spiritual reality that transcends the temporal world.

Biblical Foundation
The Bible presents true life as a gift from God, accessible through faith in Jesus Christ. In John 10:10, Jesus declares, "The thief comes only to steal and kill and destroy. I have come that they may have life, and have it in all its fullness." This verse highlights the contrast between the destructive intentions of the enemy and the life-giving purpose of Christ's mission.

Eternal Life
Eternal life is a central aspect of true life, emphasizing its everlasting nature. In John 3:16, the promise of eternal life is made clear: "For God so loved the world that He gave His one and only Son, that everyone who believes in Him shall not perish but have eternal life." This life is not merely an unending existence but a quality of life that begins in the present and continues into eternity.

Spiritual Rebirth
True life involves a spiritual rebirth, as described in John 3:3, where Jesus tells Nicodemus, "Truly, truly, I tell you, no one can see the kingdom of God unless he is born again." This new birth is a transformation that occurs when an individual places their faith in Christ, resulting in a new creation (2 Corinthians 5:17).

Union with Christ
The believer's union with Christ is fundamental to experiencing true life. In Galatians 2:20, Paul writes, "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 up for me." This union signifies that true life is lived through the indwelling presence of Christ.

Abundant Life
True life is characterized by abundance, as seen in the aforementioned John 10:10. This abundance is not necessarily material wealth but encompasses spiritual richness, peace, joy, and fulfillment found in a relationship with God. Philippians 4:19 assures believers that "my God will supply all your needs according to His glorious riches in Christ Jesus."

Life in the Spirit
Living by the Spirit is integral to experiencing true life. Romans 8:6 states, "The mind of the flesh is death, but the mind of the Spirit is life and peace." The Holy Spirit empowers believers to live in accordance with God's will, producing the fruit of the Spirit (Galatians 5:22-23) and enabling them to walk in true life.

Contrast with Worldly Life
True life stands in stark contrast to the life offered by the world. 1 John 2:15-17 warns against loving the world and its desires, which are fleeting. Instead, those who do the will of God abide forever, experiencing the true life that is rooted in divine purpose and eternal significance.

Conclusion
True life, as revealed in Scripture, is a profound and transformative reality that begins with faith in Jesus Christ. It encompasses eternal life, spiritual rebirth, union with Christ, and a life empowered by the Holy Spirit. This life is abundant, fulfilling, and distinct from the temporal and often empty pursuits of the world.
