What does the Bible say about having life in Christ?

The Bible clearly emphasizes that possessing a relationship with Jesus Christ is essential for eternal life. 1 John 5:12 affirms, 'He who has the Son has life; he who does not have the Son of God does not have life.' This verse underscores the importance of recognizing Christ as central to salvation. Without Him, there can be no true life, reflecting the sovereignty of God's plan for salvation through His Son.

Furthermore, this relationship is not contingent on theological debates or understanding every aspect of doctrine. Instead, it focuses on a personal connection with Christ as the means to salvation. Thus, a person’s assurance of eternal life is grounded in their faith in Jesus rather than their grasp of complex doctrines. This reinforces the idea that believing in Christ is paramount above all else.
