Freed by Grace

And so the Lord says,
    “These people say they are mine.
They honor me with their lips,
    but their hearts are far from me.
And their worship of me
    is nothing but man-made rules learned by rote.
Isaiah 29:13

Legalistic people should stay in God’s church. 
For although they don’t own the church, though they behave as if they do,
it’s a hospital for dying sinners not a museum for living saints.
