I know of only one thing that IS eternal: the life that we have if we trust in Jesus Christ.
"For God so loved the world, that he gave his only Son, that whoever believes in him should not perish, but have everlasting life." (John 3:16)
"Believe in the Lord Jesus Christ, and you will be saved--you and your household." (Acts 16:31)
"Trust in the LORD with all your heart; and lean not unto your own understanding. In all your ways acknowledge him, and he shall direct your paths." (Proverbs 3:5-6)
