The Bible says all sin can be forgiven, as a FREE GIFT from God IF – this is the big IF – IF we sincerely confess our sins, desire to turn from our sins, ask God for forgiveness, and claim Jesus Christ as our substitute.
It is the worst sin of all if a person knows about this offer of forgiveness but rejects it either by conscious decision or by procrastination.
Forgiveness is not automatic, earned, or transmitted by family or church. It is a personal offer and requires personal acceptance.
Failure to accept the offer is rejection of the offer, leaving that person guilty of a lifetime of sin, with judgment coming, hell instead of heaven after death, as explained in Heaven/hell.
The Bible tells about the one sin that cannot be forgiven, sometimes referred to as the unpardonable sin, but more accurately called the unpardoned sin.
This means that Christ’s substitutionary death covers every sin except this one.
This fatal sin is rejection of God’s offer.
This is the one sin we must not commit!
In other words, if we don’t commit this sin, we get forgiveness of all other sins
It's only within the last 60 years that science has acknowledged that the earth has NOT ALWAYS EXISTED but rather had a formless beginning from massive external power, just as the Bible has said all along.
It's highly unlikely that any writer three thousand years ago could know about the big bang without divine revelation from the designer/creator.
Scientific comfirmation increases confidence in the Bible and provides another REASON for Christian faith.
