v20 Timothy, God has chosen to give you his message to tell people. You must be like someone who keeps that message safe. Stay away from people who say a lot of wrong things. Those things are not about God, and they mean nothing. Some people argue against what is true. They say that they know special, secret things. But they do not really know anything. v21 Some of the people who believe those secret things have stopped believing the true message about Christ.
I pray that God will continue to be very kind to you, Timothy, and to all those believers there with you.
