19keeping your faith [leaning completely on God with absolute trust and confidence in His guidance] and having a good conscience; for some [people] have rejected [their moral compass] and have made a shipwreck of their faith.
19Then you will hold on to faith. You will hold on to a good sense of what is right and wrong. Some have not accepted this knowledge of right and wrong. So they have destroyed their faith. They are like a ship that has sunk.
