For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. For God did not send his Son into the world to condemn the world, but to save the world through him.
John 3:16-17
Some people become repulsed by the idea of eternal life because they find their lives are quite miserable. They cannot imagine "prolonging the agony." But eternal life is not an extension of a person's miserable, mortal life; eternal life is God's life embodied in Christ given to all believers now as a guarantee that they will live forever. In eternal life there is no death, sickness, hate, pain, sadness, or sin. When we don't know Christ, we make choices as though this life is all we have. In reality, this life is just an introduction. When we receive this new life by faith, we begin to look at things differently and evaluate all that happens from an eternal perspective.
God bless you,
