Because of our sins, we deserve to die. But Christ took our place on the cross and paid the death penalty that, otherwise, rested on us. He, being innocent, took on our guilt and received our punishment so that we, being sinful, could be declared innocent. Through Him, instead of perishing we receive eternal life. John 3:15 makes this amazing promise to us. It says that whoever believes in Him should not perish but have eternal life (NKJV), a promise repeated at the end of John 3:16.
Some think that, even after accepting Christ as Savior, the promise of everlasting life will be real only after His second coming. However, the promise of salvation is expressed in the present tense: He who believes in the Son has everlasting life (John 3:36, NKJV). Whoever believes in Christ has everlasting life now, and shall not come into judgment in the final day, but has passed from death into life (John 5:24, NKJV). Thus, even if we die and sleep in the grave, this temporary rest doesn’t take away from the reality of eternal life.
When Jesus becomes our Savior, our life acquires a whole new meaning, and we can enjoy a richer and a fuller existence. I have come, stated Jesus, that they may have life, and that they may have it more abundantly (John 10:10, NKJV). Instead of transitory worldly pleasures, which fill us up without really satisfying us, He offers us a life lived in a completely different way, full of inexhaustible satisfaction in Him. This new abundant life includes our whole being. Jesus performed numerous miracles to restore the physical life of many people. But above all, He wanted to give them a renewed spiritual life, clean from sin, filled with faith in Him and the certainty of salvation.
Meditate on the concept of eternal life. It is not only an imperishable existence but above all a blessed, satisfying, and happy life in loving communion with God in the new earth. Although we are still living in this world, how can we start to enjoy, even partially, what it means to have eternal life?
