GOD/BIBLE guarantees Eternal Life in Heaven for Anyone and Everyone who REPENTS his/her SINS and accepts, believes and confesses LORD JESUS as their LORD and GOD, getting baptized in the name of the FATHER, SON and the HOLY SPIRIT and continue to live a Godly life in CHRIST. My friend, I sincerely believe that and recommend you to know that and believe that. But some folks argue, that BIBLE may not be GOD's word or what all it says may not be true; even in that case, here is some wisdom; What if BIBLE is true and you were wrong, will you ever get one more chance to repent, accept, believe, obey GOD and be baptized and live a Godly life and be qualified for eternal life, once dead and gone?! Consider this, it will Never Ever Happen. BIBLE simply counsels us to live a GOD centered good life and NOT to commit any unjust, immoral, illegal, indecent things or SIN. Be wise. Be prepared. Be saved and safe. When compared to eternal life in heaven forever and ever; the pains, problems we may have to face or take to please GOD, during your short life on earth: is less than negligible.
