The legalistic mind will see legalism behind every door, except their own.
They will accuse one who teaches Grace of being legalistic about Grace. Painting the freedom you speak of into a requirement of a new law. Unbending.
Any subject disagreed upon will be looked at, from their point of view, as an attack.
Instead of seeing you "sharing" an opinion, they will see it as "forcing" an opinion.
Please pray for the legalistic mind.
