BA: Preference or Sin?
So here is what I need to ask you: Is it merely your preference to change or have you been convicted by God’s Spirit, knowing that Scripture lays out clear guidelines about sexual intimacy outside marriage? Your answer to that question will make all the difference in your ability to “go back” and draw a new line of behavior. If it is merely personal preference, it will be very difficult to draw new boundaries, because they’re arbitrary. But if what you’re sensing is godly conviction, then there is hope for change, and your reaction should be repentance, not a change of preference.
