UNIQUENESS of JESUS:

• Fulfilling of Prophecy:
  Jesus fulfilled all sixty-one prophecies in the Old Testament that refer to Him, written by numerous prophets over the span of 500 to 4000 years before His birth.  The odds against this occurring, either by His own attempts or by accident, are astronomical.  For a complete list of these prophecies and the verses they occurred in from the Old Testament, and then fulfilled in the New Testament, click here.
  
• No Known Sins:
  With all of the enemies and skeptics of Jesus' day, there is no documentation of any wrongdoing, fault, or fraud about Him.  Because it is written and because there is no evidence anywhere that it is not true, we can safely say that He was without sin.
  
• Miracles:
  In front of many, sometimes thousands of people, Jesus performed many miraculous acts.  In doing so he conquered demons (driving them out of people), the elements (causing the rain and winds to cease and walking on water), provision (multiplying the bread and fish for the 5000), sickness (healing disease and other ailments), death of others (raising Lazarus from the dead).
  
• Claimed to be God:
  Not only did He claim it, but he acted accordingly.  He knew all (about His future, about God, about other people), He controlled the elements, He healed the sick and the dead, He forgave people's sins, He was not controlled by even death.
  
• Resurrection:
  Jesus conquered death.  He appeared to many witnesses after being killed by method of crucifixion. Let me repeat that:  Jesus conquered death.  There is no other religion that I know of which can confidently claim such a victory.
  

RULES vs. RELATIONSHIP:
Christianity is unique in that the spiritual emphasis isn't (or shouldn't be) on rules that must be obeyed, but on the ability to have and nurture a personal relationship with our creator, giving thanks to His son for making it possible.  We choose to follow the rules to avoid God's wrath on us while we're here on Earth and out of respect and appreciation for the grace that God has given us, not to obtain salvation after death.
 

GRACE and FAITH vs. WORKS:
At first glance, this may seem similar to the above statement (rules vs. relationship).  However, here I'm talking about the path to the ultimate goal, life after death, whereas the above paragraph is referring to our life and relationship to God while here on earth.

Many other religions emphasize and necessitate the following of rules or works in order to reap the rewards of the afterlife.  Christianity though states that you will get to heaven by repenting of your sins, and by having faith in Jesus Christ as the sacrifice for those sins.  The works are performed only as a result of your salvation, not to achieve salvation.
 

TRINITY:
The belief that God exists in three distinct forms is also unique to Christianity.  Yes, I know the word "trinity" is never mentioned in the Bible.  It's simply a word that is used to define the three persons in the Bible that God presents himself as.  No, this is not polytheism (the belief in more than one God).  I'm talking about just one God, in three forms.  Father, Son, and Holy Spirit.  The analogy I've heard the most is that God is like water which is able to have the form of steam, water, or ice.  Another way that perhaps can help understand it (yet is not a very good analogy) is that I, as a man, can be a brother, a son, and a father all at the same time.  I am still myself, but I present myself differently at different times, or even to different people at the same time.
