We know we have eternal life in Christ when we believe in Him and confess Him as our Lord and Savior.
Eternal life in Christ is guaranteed through faith and continual reliance on Him. In John 6:53-54, Jesus emphasizes that 'whoso eateth My flesh and drinketh My blood hath eternal life.' This metaphor of eating and drinking signifies an ongoing relationship with Christ, suggesting that those who trust in Him continually embrace Him as their sustenance. The act of believing is critical; as we come to Christ, we express our faith and establish a union with Him. This union is characterized by redemption, justification, and sanctification—all gifts of grace. Assurance of eternal life is not based on our works, but solely on faith in Christ's redemptive power.
