Bible/God guarantees eternal life in heaven for anyone who 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. Personally I sincerely 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. Bible simply counsels us to live a God centered good life but not to commit any immoral, illegal, indecent things/sins. 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, take to please God, during our short life on earth: is less than negligible.
