“The good man brings good things out of the good stored up in his heart, and the evil man brings evil things out of the evil stored up in his heart. For out of the overflow of his heart his mouth speaks.” Luke 6:45
“He made no distinction between us and them, for he purified their hearts by faith.” Acts 15:9
“This is how my heavenly Father will treat each of you unless you forgive your brother from your heart.” Matthew 18:35
Obedience, speech, and forgiveness come from the heart. This is talking about real obedience, real forgiveness, and edifying speech from a purified heart filled with good things.
There are acts that look like obedience, and words that sound like forgiveness. We want the appearance of purity more than we want purity.
