Our recent Youth Conference in Masaka, Uganda stirred up a number of questions. We solicited Questions from Students to see if they were tracking with our Discipleship. The following question(s) were given to us, and I would prefer to label our reply as insights, mainly because only God himself knows the complete answer to these excellent questions.
Example Question: Did Adam have a belly-button?
Example Insights: It appears in the bible that Adam was created in a mature state, able to communicate, work, and practice critical thinking skills. He never would have had an umbilical cord since he was never a baby. Ultimately, we just don't know if God created him with or without a belly button. It would have been interesting if he did not have one, because he may have had the final word on all arguments for nearly an entire millennium - simply by pulling up his raw-hide shirt and saying something like, "no belly-button, I-am-Adam" (pointing to his abdomen without a belly button as evidence of being 1st). In like manner, maybe Eve would have slugged him in the side - reminding him of his spare rib - and that she too (showing her mid-drift) also did not have a belly-button). But again we do not know, from a biblical perspective, whether they had belly buttons or not? And, in the large scheme of things it doesn't matter. So too, when we look at many of our unanswered questions of the bible; origins, angelic order, etc... we are only given what God considers important, necessary, and complex enough for our finite minds - not simply to tease our trivial pursuits...
Question:
Is Jesus Christ really God, or the Son of God because Muslims have always challenged us "Christians"? How is the Trinity justified - yet the bible states there is only One God, according to the 10 commandments?
Insights:
The same question was purposed by Jesus at the peak of his public ministry. (Matthew 16:13f)
"Who do people say the Son of Man is?" some say a John the Baptist, some say Elijah, still others say Jeremiah or one of the prophets... "but what about you who do you say I am?"
Peter Answered, "you are the Christ/Messiah, the Son of the living God."
Soo in one quick dialogue we observe the nature(s) of Jesus. He is both fully Man and fully God.
That is why the Virgin Birth makes since - Jesus was conceived by Mary and the Holy Spirit.
Furthermore, the plural nature yet one essence in Genesis 1 makes sense "let us make man in our image, in our likeness"
More Confirmation:
Col. 1:15 He (Jesus) is the image of the invisible God, the firstborn over all creation. For by him all things were created; things in heaven and on earth, visible and invisible...all things were created by him and for him, He is before all things, and in him all things hold together
Hebrews 1:3 The Son is the radiance of God's glory and the exact representation of his being, sustaining all things by his powerful word.
John 14:5-11 ...I am the way the truth and the life. No one comes to the Father except through me,
If you really knew me, you would know my father as well. From now on, you do know him and have seen him...Anyone who has seen me has see the Father. How can you say show us the Father? Don't you believe that I am in the Father, and that the Father is in me? The words I say to you are not just my own. rather, it is the Father, living in me, who is doing his work. Believe me when I say that I am in the Father and the Father is in me; or at least believe on the evidence of the miracles themselves...
While trying to reason thru the Trinity - no illustration is perfect and they all fall short in trying to describe the Trinity, and more directly Jesus as fully God. Perhaps you have seen water (one substance that is seen as solid (ice), liquid, and gas. Or perhaps you have seen an egg described as 0ne egg but 3 parts (shell, white, yoke). Or maybe Identified ones earthly Father, that is at the same time, a husband, and a son.
Circle Square Triangle
My favorite illustration is the circle, square, triangle. It is one object yet it is 3. The stencil shows that it must perfectly fit the description of a Circle- and when I describe it - the Circle relays the idea of God the Father as infinite like a Circle without beginning or end, the Father is all powerful, all knowing and is everywhere all the time. the Circle best describes the Father in his fullness - bringing his master plan full Circle in the fullness of His time. 
Circle
The Square has Four Sides each side is a perspective of Jesus (the son) Life. The bible gives us these Four perspectives through the eyes of Matthew, Mark, Luke, and John. Four different perspectives yet describing the one life of Christ.
Square
Mathew as a government worker (tax man) relays Jesus as King - we see him visited by the Magi, entering Jerusalem in Peace as a King on the foll of a donkey, and above his head on the cross a placard that reads King of the Jews.Mark as a servant, and mostly a kin of Peter relays Jesus as a humble Servant... Mark records for us the simple theme that Jesus came to serve not to be served, but to be a ransom for many.
Luke we know thru his association with Paul, and thru his pen writing to Theophilus (Books of Luke & Acts), he was a physician. A doctor who with great detail gives us the perspective of Jesus as the Son of Man. We see his frailty and humanness, and the limitations he had as one of us - mankind.
John one of the closest earthly friends/companions gives a very different perspective. It is to John, who wrote the 4th gospel, three letters, and the final Revelation of Jesus that we receive a picture of Him as the Son of God. The divine nature and admission through the powerful "I Am" statements that Jesus is fully God.
Triangle
Finally the Triangle represents the Holy Spirit. The transformation of our lives happens thru His spirit. Love, Joy, Peace, Patience, Kindness, Self-Control and soo on happen in our lives vertically as we connect to God (Vertically) thru His spirit. Likewise, we love our neighbors (Horizontally) thru an eternal capacity and selflessness only thru the Holy Spirit.And so Just as the Circle Square Triangle is distinctly Three it is also One in Essence. Trinity 3 in 1

Circle Square Triangle
This is me attempting to describe the Triune but Monotheistic Infinite God in a very finite/concrete/simplistic way... by the way the concept is all over the scriptures but the word Trinity or Triune - not in there - again our best attempt to describe the indescribable.
This Illustration also falls short in a number of ways, but it stirs in us a concrete way to believe that something (ex. Circle Square Triangle) may Exist though it was hard to wrap your mind around it - until after we saw it - not only as 3 Dimensions but 1 in Essence -
...so too it is difficult to understand there is
1 God in essence (Nature) while maintaining 3 distinct persons (entities) simultaneously
NOT 3 Gods who have different roles to play depending on the dispensation of time within their intermittent divine intermission when man kind needs adjusted (Pluralism)
NOT 1 Person who has merely manifested himself in these three modes at various times - giving up the persona of one to become the persona of the other (Modalism)
Islamic studies does not allow the distinctiveness of 3 persons or a shared nature in their mono theistic view. Jewish scholarship does allow for it - hence the Messianic undercurrent of their Tanakah (Law, Prophets, Writings)
