What does the Bible say about eternal life before the world began?

The promise of eternal life was made by God before the world began, as highlighted in Titus 1:2. This underscores the unchanging nature of God’s promises and the assurance believers have that, through Christ, they have been granted eternal life. The concept of eternal life here refers not just to longevity, but to a relationship with Jesus Christ, who stated in John 14:6, 'I am the way, the truth, and the life.' This life, according to the Reformed theology, is a gift that believers possess even before their physical existence, being rooted in God's eternal purpose and love.
