Will a person go to hell if they've never heard the gospel? And the answer is yes.
You see, there is no alternative to the gospel. Jesus Christ said,
I am the way, the truth, and the life, and no man cometh unto the Father but by me.
But what about those who have never had the chance to hear it?
Well, number one, that's why it's important that churches actively go soul-waning
in order to give people the chance to hear the truth.
But number two, the Bible actually says that Jesus Christ is that light
which lighteth every man that cometh into the world,
essentially stating that God is embedded within every human being,
a measure of truth that he wants us to respond to,
intended to position us to eventually hear the truth of the gospel and, Lord willing, believe it.
So if a person ever hears the gospel, it's only an indicator that they rejected previous truths that were given to them.
John 3.19 says,
In this is the condemnation, the light is cometh unto the world,
and men love darkness rather than the light because their deeds are evil.
For everyone that doeth evil, hateth the light, neither cometh unto the light,
lest his deeds should be reproved.
God has given us the witness of creation, our conscience, and even the Bible.
But the truth is, most people are going to go to hell
not because they never heard the gospel, but because they heard it and rejected it.
