To speak incorrectly in the meetings is much better than not to speak

“The Spirit is always ready and expects to speak with us and through us, but we would not always cooperate with the Spirit to speak. Whenever we come to the meeting, we must try to speak. In a good sense, it does not matter whether we speak properly or wrongly, well or poorly. As long as we speak, God will be happy. Parents always like to hear their young children speak…. For many years our Father in heaven has not seen us speak much in the meetings, and this should have bothered Him. If we come to the meetings speaking, even in an incorrect way, He will be happy. To speak incorrectly is much better than not to speak. When someone speaks, even incorrectly, he is learning to minister to others.”
