Today you should read: Mark 3:20-35
Jesus has chosen His disciples, and His ministry is so well-known that He and His disciples can’t even go into a house to eat because so many people follow Him (v.20). But Jesus also had some opposition as we see in this passage. His family thought He was crazy, (v. 21) and the Pharisees thought He was demon-possessed, pronouncing their judgment of Him as the “prince of demons”(v.22).
Jesus then begins to define Himself and explain to them that He could not possibly be working for Satan because “a house divided against itself cannot stand”. Jesus then tells them that His work should prove He is from God because the only person who can “bind a strong man” is someone stronger. Only God could do such work against Satan.
Jesus then transitions to a very stiff and scary pronouncement of judgment – he tells the Pharisees that every sin can be forgiven except one: to “blaspheme the Holy Spirit”. This has been deemed the “unforgivable sin”.
What this means is difficult to say; many authors and theologians have tried for a long time to describe and define this “unforgivable sin.” This is a tough issue to wrestle with because when we read the entire Bible, it is very clear that the blood of Jesus is powerful enough to save us from all sins. To say there is one sin that is unforgivable seems to contradict that.
The important thing is to look at the entire Bible for an explanation because the Bible does not contradict itself. With that said, I believe the best explanation is that the “unforgivable sin” is the sin of essentially rejecting Jesus and His deity. We see some proof of this in verse 30 – Jesus was pronouncing judgment on them in response to their saying that He had an “unclean spirit” and, by default, denying His deity and rejecting Him as the Messiah. This explanation fits with the rest of the Bible and makes the most sense because we know that anyone who does not accept Jesus as God’s Son will not be saved (John 14:6).
The passage ends with another interesting encounter: Jesus’ family asks to speak to Him and He takes the opportunity to teach everyone with Him a very important lesson. He tells them that it is “those who do God’s will that are His true family.” This speaks volumes to the importance and significance of the church family in our lives. We should take care of our families and hold them up as a high priority, but we also need to have a special place in our hearts for our church family and those who are striving to follow after God.

Good job, Robbie. I like how you explained the unpardonable sin. Good correlation.
Thanks for the insight into the “unforgivable sin” and the rest of the summary. Be good brother
Good job with a controversial passage, Robbie. When you said, “This speaks volumes to the importance and significance of the church family in our lives.”, I couldn’t agree more! I reflected on this last night after Connect Group. Serah and I are so grateful to have the church family we have.
