No Pearls for Pigs
Do not give what is holy to dogs, and do not throw your pearls before swine, or they will trample them under their feet, and turn and tear you to pieces.
Matthew 7:6
The Scriptures are sufficient for the Christian life. They show the way of Salvation, Jesus Christ, and they instruct in righteousness, fully equipping the man of God for every work of service. The Scriptures are not the sum total of everything knowable about God of course, for Jesus Himself said that He had much more that He wanted to share that He couldn’t, because it would be too much for His disciples (John 16:12). The Holy Spirit is here to guide us into all truth. But, when that comes, the object is not necessarily to write a new book about it.
