So rejecting Jesus as your Lord and Savior (basically abandoning worship of God because of the Trinity) is said to be the unforgivable sin. But what significance does the word "unforgivable" have?
Doesn't the person who rejects Christ go to Hell anyway? What good are forgiving his other sins if he commits that? How can it unforgivable if the person dies and is at judgement with his current stance of not worshiping Christ? There is no forgiving at that moment. How can it be unforgivable if you can't be forgiven for anything in the first place during judgement?
This seems to be a paradox.
The so-called 'unpardonable sin' is clearly defined in scripture.
Hebrews 6:
Therefore leaving the principles of the doctrine of Christ, let us go on unto perfection; not laying again the foundation of repentance from dead works, and of faith toward God,
2 Of the doctrine of baptisms, and of laying on of hands, and of resurrection of the dead, and of eternal judgment.
3 And this will we do, if God permit.
4 For it is impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost,
5 And have tasted the good word of God, and the powers of the world to come,
6 If they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame.
Mark 3:28-29
28 Verily I say unto you, All sins shall be forgiven unto the sons of men, and blasphemies wherewith soever they shall blaspheme:
29 But he that shall blaspheme against the Holy Ghost hath never forgiveness, but is in danger of eternal damnation.
So the unpardonable sin doesn't apply to those who don't or won't receive Christ, but those who have and gone back into the world having been saved from the world. Verses 4-5 of Hebrews 6 makes clear the sort of person the unpardonable sin is referring to. Those who:
Were once enlightened,
Tasted the heavenly gift,
Were made partakers of the Holy Spirit,
Tasted the good word of God,
And the powers of the world to come.
In verse one Paul adjures believers to
go on to perfection. Even today there are many who stop learning as soon as they are dry from baptism. They are in danger of becoming like the seed that sprung up quickly but had no depth of root, and perished.
Paul further instructs to 'make your calling and election sure', and, 'study to show yourself approved', etc.
There are many who leave the church who were never really in the church to begin with thus not guilty of the unpardonable sin.
