Just as your friends know something of your life, they don’t know all the things which have happened in your life.

  Dr. Luke focused on Jesus as the Son of Man: fully Man; (yet, Son of God: fully God).
Dr. Luke did not include everything which happened to Jesus, Mary and Joseph while they were living in Bethlehem.  He did not record the attempt on the Child Jesus’ life by King Herod and how His parents were told to go to Egypt for a time by God.  Matthew told about that in his book.  (See Matthew 2:1-23)

Dr. Luke’s message was written primarily for Gentiles.  Matthew’s message was written primarily for the Jews.  So they included the facts of Jesus’ life which would be of interest to their audience.
Both told of Jesus and both omitted parts of His history.  Leaving out parts of your history as you talk or communicate with others is not wrong as you emphasize a specific focus.  It depends with whom you are talking, and what is important to your conversation doesn’t it?

Omissions may be deceptive, intentionally deceptive.  And when used in that way omissions become a lie.
Omissions may sometimes be intentional discernment and done with wisdom to keep the main focus on the main points.
Omissions can be used for wrong purposes (deception) or used for wise purposes (discernment).

When you purposely omit something from your communications are you intentionally being deceptive or are you using discernment?

Godly wisdom is pure, peaceable, gentle, reasonable, full of mercy, full of good fruits, unwavering and without hypocrisy…this is the measuring rod for omissions.
(See James 3:17 NASB)

 

When you omit something from your communication:

are you practicing discernment with Godly wisdom

or being intentionally deceptive?
