I can't believe such a topic has taken up so much space on a forum about sharing the Bible's message of hope and God's plan for Salvation. As has been covered (frequently) there is no distinction between sins of omission or sins of commission. All sin is repugnant to God.
Although all sin is equally repugnant, blasphemy can in one case (but not all cases) make forgiveness impossible. That doesn't mean it's more hideous necessarily just that it erects an insurmountable wall between The Holy Ghost and the divine ministry through which Redemption is mediated.
The link shows full context which it's always important to consider. What does it mean to be against Jesus? Again we find the answer in God's Inerrant word. Obsessions not in accordance with what God has explained oppose Jesus because God
is Jesus. Perfection was impossible before God arranged His conception, birth, torture and death. This is clear from what we can read in The Bible. Now we live in a different world, where the Blood of Jesus has mingled with the sod below as a matter of history. There was a time when that was a future event the world

The Bible is always consistent. We can be assured of this from the witness of both the Psalms and the Proverbs. Perhaps you could try out the search function for those references? So it's important to appreciate what God communicates to His creation, especially now that we're in the last days. Jesus could return at any time. The following passage from Deuteronomy may be helpful for you or for anyone else in a similar pickle.
In all the links you can see
A] what the link is and
B] complete context at a glance without the need for extra clicking. Thank you for contributing to the thread and although it's getting a bit off topic I'm sure that God's true nature will be evident in the linked verses. Satan would love to select everyone for maximum torment, far worse than seeing loved ones caught in agricultural machinery or any infestation of skin lesions imaginable even to the most depraved barbarian but happily that choice has already been made. By God.
Praise Jesus!
