In actual fact, a funeral service is not for the deceased. It is primarily for the family and friends; and while a Christian minister may be called upon to conduct the service, he must not be guilty of suggesting that the unredeemed will inherit eternal life. To do so is to be disingenuous at best and dishonest at worst.
If a pastor is true to the Word of God, he cannot change or minimize the Bible’s warning that the consequence of unbelief is condemnation (John 3:18).
To suggest or hint that someone who has never been saved is somehow headed for heaven does nothing but confuse the mourners and give the false impression that one can go to heaven without trusting in Christ who is the only way to God (John 14:6).
The carefully-crafted remarks of a Christian minister can convey the Gospel message of hope and certainty to those who need it most.
