And we know that the Son of God came so we could recognize and understand the truth of God—what a gift!—and we are living in the Truth itself, in God’s Son, Jesus Christ. This Jesus is both True God and Real Life. Dear children, be on guard against all clever facsimiles. (1 John 5:21 MSG)
Communication is both an expressive, message-sending, and a receptive, message-receiving, process. Failure to communicate effectively can be due to a problem on either or both ends of the process. Say what you mean and mean what you say. Be direct and honest; don't dance around the issue or play games.
