I don’t imagine that anyone sets out to become a legalist and yet a great many God-fearing, Scripture-loving, holiness-seeking people inevitably seem to end up there.
It happened to the Pharisees in Jesus’ day.
They didn’t set out to miss the heart of the law; they didn’t set out to become blind guides to the blind or to take away the key of knowledge, and yet, according to Jesus, that is exactly what they ended up doing.
Obviously legalism is something we need to maintain a constant guard…
