Q. Thank you for your wonderful site. I attempt to lead an adult SS class and there are questions we have about 1 John 5:16,17. When John says that we should pray for those committing a sin that does not lead to death, (what is that sin? – I thought all sin lead to death) and then he is saying that we should not pray for our ‘brother’ who commits the sin that is leading to death – (what is that sin?).
