It's one thing to know about someone; it's another thing to know them intimately. Both are important, yet isn't the latter greater? John writes to believers to remind them of facts they should know - and yet that's just to reconnect them to the One whom they know personally: truth, eternal life, God Himself, in Jesus Christ. He came to be known, not just known about. Pastor Kyle O'Donnell preaches on 1 John 5:13-21.
