Whenever the topic of the unforgivable sin comes up, people tend to ask two questions about it. First, what is it? Second, have I committed it? This Sunday we will look at Jesus' stern warning to the Pharisees about blaspheming the Holy Spirit. We will see that this sin is not about a one time action but rather a numbness of the heart to the work of the Holy Spirit over time. Let us heed Jesus' words as we examine our own hearts this Sunday.
