Q. How Can I Know If I’ve Committed the Unpardonable Sin?
A. UNPARDONABLE SIN is just an expression not appearing in the Bible, but based on certain passages such as Matthew 12:31, where Christ teaches that “blasphemy against the Holy Ghost shall not be forgiven unto men” (see also Luke 12:10). This assertion was made in response to a statement by certain Pharisees who, after witnessing a healing performed by Jesus, said that He “cast out devils … by Beelzebub the prince of the devils” (Matthew 12:22-24; Mark 3:22-30).
The Holy Spirit impresses truth upon the mind and heart and convicts of sin (John 14:17 & John 16:13). Numbers 14:28 describes God as “long-suffering and of great mercy.” 2 Peter 3:9 confirms that God is longsuffering and adds that he is “not willing that any should perish, but that all should come to repentance.” His Spirit will not continue to strive indefinitely with the hard, stubborn heart (Genesis 6:3). When the promptings of the Holy Spirit are persistently resisted and refused, the person is left in darkness.
Does that mean that the person can never be saved in God’s Kingdom? Absolutely not. The words of 1 John 1:9 tell us, “If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.”
How can a person know if he has committed the unpardonable sin? There is a simple and easy answer. Anyone who is still being convicted of sin and feels a drawing to God has not grieved away the Holy Spirit.
