One of our biggest mistakes we make is that we sometimes answer people too quickly, just giving them something off the top of our head. Only a fool utters his whole mind (see Proverbs 29:11) Those who speak frequently and hastily are always in trouble, as the Bible says, "There are those who speak rashly, like the piercing of a sword, but the tongue of the wise brings healing" (Proverbs 12:18).
Jesus operated in wisdom. He always knew just the right thing to say, at just the right moment, to astound everybody, If we don’t spend enough time with God, we will say the wrong thing at the wrong time, Decide to wait on God before speaking your mind today.
Proverbs 8:6 ~ (KJV)
Hear; for I will speak of excellent things; and the opening of my lips shall be right things.
