The first memories of my spiritual life come from visiting Russian Orthodox churches for funerals (I only went to one Catholic funeral growing up) or Saint feast days. I was presented with the beautiful surroundings of icons and candles, incense and peaceful quiet that was heavy with holiness. These churches first presented to me the notion that God was not just up in heaven, sitting on the clouds, but ever present in this holy surroundings, set apart specifically for His worship. Other memories, much more normal every day type stuff, come from having discussions (sometimes around the kitchen table or in the car) with my Mom and her presenting her knowledge of the Bible. Those discussions led me to want to read the Bible and see if what Mom was saying was really what Jesus had said or done.
Okay so..
Trinity: God the Father, God the Son, and God the Holy Spirit. One in three: three divine Persons in one divine nature.
Incarnation: God becoming human. Jesus Christ was fully God and fully human. Christ became the sign that would make God known to humanity and make it possible for humanity to be touched by God.
Redemption: Humanity's redemption comes from Jesus Christ. Christ paid the price of His own sacrificial death on the cross to ransom us, to set us free from the slavery of sin.
In order to understand Jesus more fully, we need to look at each of these doctrines. Jesus was born without original sin and had the ability and power (since He was God-- Trinity) to do the impossible for humanity: live a sinless life as a human being (Incarnation). And its because of Him living a sinless life (something each Christian strives to do in their own lives) that humanity has salvation-- a gift freely given to each individual who calls on Christ as his/her Savior and strives to be holier and holier through God's grace (Redemption).
Looking over the chapter again it mentions a verse I would want to point out again:
John 1:14-- Jesus "became flesh and made His dwelling among us."
I think that's a wonderful expression of God's love for us that He would care enough to live among us, live a life of work and play, and be willing to live a life of hardship and pain too.
Other verses that come to mind are the following:
Matthew 5:43-48 which talks about loving your enemies.
The various verses about Jesus and His disciples healing people: Matthew 8.
Matthew 11:36-- At the sight of the crowds, His heart was moved with pity for them because they were troubled and abandoned, like sheep without a shepherd."
Jesus' actions through out the Gospels tell much of His love for humanity. Even when He showed anger (such as in the temple where He overturned tables) it was to teach a lesson about how to truly love God for the sake of having a righteous relationship with Him.
