Many times we quench the Spirit by not allowing Him to speak. We become concerned that what we hear may not be from the Holy Spirit, but be from the enemy instead. So we shut down the avenue of communication. Instead, we should be open to communication, testing what we receive to insure it is from God. God wants us to hear from Him. He will help us discern what is from Him and what is from the enemy. The answer is in the testing, not in quenching.
1 Thessalonians 5:19-22 – Do not quench the Spirit. Do not treat prophecies with contempt but test them all; hold on to what is good, reject every kind of evil.
