Two points are given here about how the “righteous” (6662) speaks.
The first is that we should always speak from the “heart” (3820). There is a consistency that is a part of the upright life. We say what we believe. We behave to an inner standard. To use a cliche, we “practice what we preach.”
Because the change that has taken place in us is not just a superficial whitewash. When the blood of the Lamb cleanses us and the Holy Spirit fills us, it is a cleansing that goes all the way through. It goes all the way to the heart. It was the measure that was held up to the early church to prove that gentiles were accepted by God.
(Acts 15:9 KJV) And put no difference between us and them, purifying their hearts by faith.It starts in our core. If that isn’t changed, nothing will stay changed.
So? If you aren’t there, call on God. If you are, rejoice and let it control all of you.
