God can forgive all sin,
except one - ‘unpardonable sin’. All
wrongdoing is sin, and there
is sin that does not lead to death.
“If you see any brother or
sister commit a sin that does not lead to death, you should pray and God will
give them life. I refer to
those whose sin does not lead to death. There is a sin that leads to death. I am not saying that you should pray about that. All wrongdoing is sin, and there is sin that does not lead to death.” (1
John 5: 16-17)
‘Sin’ that can not be
forgiven by God is ‘rejection of God’s only Son Jesus Christ’. This ‘sin’ leads
to eternal ‘death’ or condemnation. “..
whoever does not believe stands condemned already because they have not
believed in the name of God’s one and only Son.” (John 3:18) John may also
include some other ‘sin’ here.
May God be always with you.
