Eternal life is NOT something we achieve on our own merit. The Holy text says God loved us so much that HE GAVE HIS one and only Son. There are no special requirements. The Holy text says WHOEVER BELIEVES in Him shall not perish. That belief and confidence in only what God has done for us is why they call it saving Faith or Faith that Saves. Society likes to add all those special things, rules, requirements to make you think you have to be good enough. Not so! Jesus finished it on the cross. He said IT IS FINISHED.
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. John 3:16
