First, God does not have to save anybody. You cannot compel God. Everything is only by the benevolent grace of God. Unearned. God shouldn't necessarily save you but God graciously does, not by you compelling Him. We can claim God should save us, as I alluded to in my earlier post, but it's a claim that has zero substance.
Second, acting in bad conscience, knowing something to be true but not following it out of convenience, is damnable. Follow an informed conscience. Follow it even if it is not perfectly formed.
Truth matters. People who err might be saved, at God's pleasure. People who act in bad conscience I think would be far worse off. Being convinced you are in the wrong church but staying there for the sake of the opinion of your parents or your job would be damnable. You know the truth but you just don't have the courage to follow it. That's convenience over truth. That's a Protestant minister who won't become Catholic because she's got a nice pastoral position and she has no path to becoming a Catholic priest. She should do it anyway. That's a Catholic priest who no longer believes what the Church teaches on faith and morals. Staying and pretending is reprehensible. Truth matters but following one's conscience matters more. Inform your conscience, trust God, and follow your conscience. Don't stay out of convenience.
Informing your conscience is key here. That differs from just conveniently accepting something you read once on the internet. Most of us are happy with our status quo and studiously avoid anything that might rock the boat. We should be able to figure out where we are in error but we just don't want to get all unsettled. Informing one's conscience is to take risks and learn things. Sometimes they are true and compelling things. Follow them. THAT is how following truth and following what we believe to be true actually converge.
