In Isaiah 9:6, four important names of Jesus were revealed (i.e. Wonderful Counsellor, Mighty God, Everlasting Father, Prince of Peace).
The name 'Wonderful Counsellor' might be the easiest to digest and identify with - since even non-believers would, most of the time, agree that Jesus' teaching is 'good', and He seems to be a 'wise teacher', Someone whom we can receive counsel.
However, for the second name, contrary to what the Muslims and Jehovah Witnesses claim (that Jesus is not God), the verse so-clearly declare that Jesus Christ is the 'Mighty God'! There is not doubt about it. He is God, and not just any God, but the mighty God.
The third name is the most intriguing to me. If I'm not wrong, I believe this is the only time in the Bible where Jesus is actually referred to as 'Father'. (The closest it got in the New Testament was when Jesus said that He and the Father are one - but never has Jesus held any title/name with the word 'Father' in it). A theological discussion at this point might be helpful (or not?) and it could go deep and/or off tangent, but I believe the reason Jesus was called 'Father' is exactly because He and the Father are one. This is in fact an astounding verse that shows the intimacy and intricacy of the Father-Son relationship in the community of the holy Trinity.
And last but not least, I think the fourth name is what many of us subconsciously tend to downplay when we exalt Jesus as the Mighty God. Just as the Lion of Judah, Jesus is also the Lamb of God. Hence, just as the Mighty God, He is also the Prince of Peace. We need to hold the names in tension of each other for a full worship of God (relishing God in both fear and love), and for a better comprehension of the operation of His will in our world today.
How about we learn to meditate upon one name of Christ each week?
