Titus 1:13-14

One of the things that they were doing that was wrong was devoting themselves to Jewish myths. This is clearly wrong, yet they believe these things. Not only do they believe them, but they go as far as devoting themselves to these things. The other thing that is mentioned that they devote themselves to is the commands of people who turn away from the truth. So, now it's not one thing they're devoting themselves to, but to a person or people. Now, if this person they devoted themselves to was Jesus, then that'd be great. However, they are devoting themselves to people who turn away from the truth. It doesn't matter what these people are saying or doing, it is different from the truth and that isn't good. They could even be changing their minds constantly, but the one who devotes him or herself to this person would still be as one lead astray. This is unwise to say the least. Why would you want to follow someone who turns away from the truth? They are to be rebuked sharply, so that they are not allowed to go as far as devoting themselves to the wrong things.
