“Therefore I say to you, every sin and blasphemy will be forgiven men, but the blasphemy against the Spirit will not be forgiven men.” (Matthew 12:31)
If a person truly listens to the promptings of the Holy Spirit and asks for pardon and forgiveness that person is not guilty of blasphemy against the Holy Spirit.
Do you hear the Holy Spirit calling you to remove some walls in your life so that Jesus can freely communicate and spend time with you? Follow the promptings of the Holy Spirit right now and ask for help breaking down any wall of separation between you and God.
Any sin mankind wants pardon for is forgivable, however, if we turn our backs on the voice of the Holy Spirit we begin to silence His convictions and eventually we cannot hear His convicting power. This effectively blocks the working of God in our lives because we have reached a point where we cannot respond to the promptings of the Holy Spirit. At this stage a person can no longer ask for repentance and therefore cannot be saved.
The good news is this — if a person still desires forgiveness and confesses his sins, those sins will be forgiven. As long as you are under conviction and you want to be forgiven you are not guilty of the unpardonable sin.
