There was a lizard in the grill and I wonder where it went, my father said it ran off, but I didn’t believe him, was it a sin that I thought my father was lying?
Johnny, please get help for your scrupulosity. You cannot come here and ask if everything is a sin. You need help.
Having an opinion is not a lie. No sin
Not to believe someone’s opinion is not a sin per se.
My opinion (you can believe it or not, and i am not lying)
Be fine in Jesus
