Where the Spirit of the Lord is, there is liberty. (2 Corinthians 3:17)
"Liberty has many aspects to it, but no liberty is going to help people as much as testimony. I find people who don't know how to testify properly. We must testify only as the Spirit gives utterance. We find in the book of revelation that "the testimony of Jesus is the spirit of prophecy" (Revelation 19:10)
Sometimes our flesh keeps us down, but our hearts are so full that they lift us up. Have you ever been like that? The flesh is fastening you to your seat, but your heart is bubbling over. At last the heart has more power, and you stand up. Then in that heart affection for Jesus, in the Spirit of love and in the knowledge of truth, you begin to testify, and when you are done, you sit down. Liberty used wrongly goes on after you have finished saying what God wants you to say, and it spoils the meeting. Do not use your liberty except for the glory of God.
...Never finish up with something too long; finish up with something too short. Then everybody comes again eager to pick up where they left off."
