Don’t go against your conscience. Or your faith could be shipwrecked. 1 Timothy 1:19. Your faith is like a ship, that is meant to take you to a certain destination – ultimately heaven – but there are also divine situations that your faith can take you to in this life. If your faith is shipwrecked, your faith is broken and until and unless your faith is rebuilt, your faith won’t take you anywhere. So you could miss heaven.
So don’t violate your conscience. Don’t deliberately sin. There are very strong warnings in the Bible about the danger of wilfully sinning, and continuing in sin, without repentance. See for example Hebrews 10:26-39. It happens a lot.
