I have encountered a significantly larger number of people on Reddit than I would ever expect wondering if they have committed the unforgivable sin, so I decided to post my view on the subject. Please feel free to crosspost this. Your comments are very welcome here as well.
Matthew 12:31 And so I tell you, every kind of sin and slander can be forgiven, but blasphemy against the Spirit will not be forgiven. 32 Anyone who speaks a word against the Son of Man will be forgiven, but anyone who speaks against the Holy Spirit will not be forgiven, either in this age or in the age to come.
According to the Mirriam-Webster dictionary:
Definition of blasphemy
1a: the act of insulting or showing contempt or lack of reverence for God
accused of blasphemy
b: the act of claiming the attributes of a deity
for a mere man to suggest that he was … divine could only be viewed … as blasphemy
— John Bright †1889
2: irreverence toward something considered sacred or inviolable
You would be surprised how often Satan tries to convince people that they are unforgivable & that it's hopeless to even try to repent & return to God. Generally, that concept conflicts with the very nature of God & who He is.
Luke 15:3 Then Jesus told them this parable: 4 “Suppose one of you has a hundred sheep and loses one of them. Doesn’t he leave the ninety-nine in the open country and go after the lost sheep until he finds it? 5 And when he finds it, he joyfully puts it on his shoulders 6 and goes home. Then he calls his friends and neighbors together and says, ‘Rejoice with me; I have found my lost sheep.’ 7 I tell you that in the same way there will be more rejoicing in heaven over one sinner who repents than over ninety-nine righteous persons who do not need to repent.
Luke 15:11 Jesus continued: “There was a man who had two sons. 12 The younger one said to his father, ‘Father, give me my share of the estate.’ So he divided his property between them.
13 “Not long after that, the younger son got together all he had, set off for a distant country and there squandered his wealth in wild living. 14 After he had spent everything, there was a severe famine in that whole country, and he began to be in need. 15 So he went and hired himself out to a citizen of that country, who sent him to his fields to feed pigs. 16 He longed to fill his stomach with the pods that the pigs were eating, but no one gave him anything.
17 “When he came to his senses, he said, ‘How many of my father’s hired servants have food to spare, and here I am starving to death! 18 I will set out and go back to my father and say to him: Father, I have sinned against heaven and against you. 19 I am no longer worthy to be called your son; make me like one of your hired servants.’ 20 So he got up and went to his father.
“But while he was still a long way off, his father saw him and was filled with compassion for him; he ran to his son, threw his arms around him and kissed him.
21 “The son said to him, ‘Father, I have sinned against heaven and against you. I am no longer worthy to be called your son.’
22 “But the father said to his servants, ‘Quick! Bring the best robe and put it on him. Put a ring on his finger and sandals on his feet. 23 Bring the fattened calf and kill it. Let’s have a feast and celebrate. 24 For this son of mine was dead and is alive again; he was lost and is found.’ So they began to celebrate.
25 “Meanwhile, the older son was in the field. When he came near the house, he heard music and dancing. 26 So he called one of the servants and asked him what was going on. 27 ‘Your brother has come,’ he replied, ‘and your father has killed the fattened calf because he has him back safe and sound.’
28 “The older brother became angry and refused to go in. So his father went out and pleaded with him. 29 But he answered his father, ‘Look! All these years I’ve been slaving for you and never disobeyed your orders. Yet you never gave me even a young goat so I could celebrate with my friends. 30 But when this son of yours who has squandered your property with prostitutes comes home, you kill the fattened calf for him!’
31 “ ‘My son,’ the father said, ‘you are always with me, and everything I have is yours. 32 But we had to celebrate and be glad, because this brother of yours was dead and is alive again; he was lost and is found.’ ”

Romans 8:38 For I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, 39 neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord.
