Read Matthew 12:30-32 30
“Anyone who isn’t with me opposes me,and anyone who isn’t working with me is actually working against me. 31 “So I tell you,every sin and blasphemy can be forgiven-except blasphemy against the Holy Spirit,which will never be forgiven. 32 Anyone who speaks against the Son of Man can be forgiven,but anyone who speaks against the Holy Spirit will never be forgiven,either in this world or in the world to come. (NLT)
Over the years,a few people have come to me concerned they have committed the unforgivable sin. In each case I have confidently assured them they have not done so. Why such assurance? Simply this: if you are worried about having committed the unforgivable sin it indicates your conscience is still working,you have an awareness of the reality of your own sin and the holiness of God.
Jesus spoke of the unforgivable sin when dealing with Pharisees who were attributing his works and words to the devil. They were calling light darkness,and good evil. They were,in effect,refusing to embrace the truth Jesus was speaking. This is unforgivable in that it meant they were refusing to believe that mercy and forgiveness were being offered. Ultimately,the unforgivable sin is the refusal to acknowledge that Jesus offers forgiveness.
And this refusal persists till the last breath we take. Someone might reject Jesus’ message till the day they die but it is never too late to accept it. Perhaps this is what Jesus means when he says that speaking against him is not unforgivable. Peter even spoke against him. Difficulty in grasping who Jesus is can be overcome. Steadfast rejection of who he is cannot.
In short,we can never know if someone has committed this sin. That truth only becomes evident when they die. It may well be that some we know will commit this sin. But we will never know for sure. And as long as we are alive to what Jesus is offering and are convicted of our shortcomings,we can be sure we haven’t committed it. Those who commit the unforgivable sin are,sadly,those who never give it a second thought.
