I'm a sinner in my mind on occasion - I break some commandments in my mind all the time. I don't act on it. Do you think God can't distinguish between a passing thought and an action?
See Matthew 5:27-30. Jesus had some tough words about how our thoughts could destroy us. God surely distinguishes the passing thought that Satan loves to tempt us with, but there ought to be a complete arrest of that thought and not give it life in any way. Recognize the attack against the mind, the battlefield is in the mind first. If the enemy can get your mind, he's got your body too.
Your point about commandments in the mind is so key.
Being heterosexual is just part of who I am. I don't THINK about it, nor do I ACT on it in every waking minute, an impossibility. I believe this is true of homosexuals, too.
ALL HAVE SINNED AND FALLEN SHORT OF THE GLORY OF GOD. But, all can be redeemed.
yes.
