For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: not of works, lest any man should boast. For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them. Ephesians 2:8-10 KJV https://bible.com/bible/1/eph.2.8-10.KJV
There is no other way to be saved from an eternity in hell. His grace and faith in Him is the only way to be a saved child of the Living God! Believe it so that you can be in heaven when your eternity begins. It could be tomorrow or tonight or next year but when it comes you will know it.
