Hi,

I started meeting with the LC a few years ago shortly after I got saved.
I've been in and out of their meetings, and their ministry never really took hold in me
I always got my messages from the Bible and casually read their stuff in meetings.
However, recently I've become interested in a sister there who serves full time. The enemy came up and accused me of being in a cult, and I know the enemy doesn't want me to marry her but that made me look into the LC and it potentially being a cult. I think this sister likes me but I'm more worried about the enemy accusing/condemning me for being in a cult.
I'm concerned about this, can anyone offer advice?
