"You can listen to Jimmy, but you can't hear him"

There are a few members of my small group and family who are choosing idols. The most common one they choose is the false deity they look at in the mirror every morning. God has placed a very hard word on my heart for them, but the enemy is doing a good job of continuing to make their own reflection very appealing and distracting.

I am stuggling with a conflict of delivering God's word with His grace or picking up the rock and smacking them on the head with it.
