NOT SAVED ON EARTH, CAN’T BE SAVED IN HEAVEN
No one who is not saved from sin here on earth can be saved from hell hereafter. No one can see the kingdom of God above unless the kingdom of God is manifested in him here on earth below. Whoever will reign with Christ in heaven, must have Christ reigning in him here on earth. So, whosoever denies Christ on earth will be denied in heaven. Jesus said He would be ashamed of anyone who is ashamed of Him; call it a pay-back! (Luke 9:26).
Unfortunately, as true as this is, and as clearly written and emphasised in the Scripture among other truths, it is ironic that no other truth is less received or ignored by men than the Gospel of Salvation through Jesus the Redeemer. Believe it or not, the only condition that must be met and fulfilled by any person(s) desirous of eternal life in heaven is salvation through Jesus. Everyone must confess Jesus as Lord and accept Him as Saviour in order to make heaven.
Therefore, rejecting Jesus as the Saviour is rejecting God, His grace for redemption and eternal life in heaven. Jesus is the way, the truth, and the life: no man comes unto God but by Him. (John 14:6). It is also true that there is no salvation through anyone other than Jesus because there is no other person in heaven and on earth by whom a Man could be saved. (Acts 4:12).
