Christianity began around 2000 years ago in Judea (present-day Israel) with Jesus Christ and his faithful group of disciples. During this time, Judea was a cross-cultural mecca or capital of bustling cities and farms.At this time Jews hated the Roman's rule because of the of the historical oppression or suffering they faced as a people. The polytheistic cultural beliefs of Rome were also pagan and intrusive to Jewish life. Some Jews saw that their only hope was to conform to this change. Others became religious zealots who formed pockets of guerrilla resistance against Rome. Still others withdrew themselves into the Judean wilderness to study the Jewish law and wait for the eventual coming of their promised Messiah (savior).
The Arrival of the Messiah:
With this cultural and religious story, the ministry of Jesus began. Jesus was a Jew. He observed the Jewish faith and was well acquainted with the Jewish Law. In His early thirties, Jesus traveled from village to village, teaching in the synagogues and healing those who were suffering. Jesus' teaching was revolutionary. He challenged the established religious authorities to repent from their self-righteousness and hypocrisy and realize that the Kingdom of God is rooted in service and love. Jesus' teachings stirred the hearts of people and created instability, something the Jewish religious authorities feared. Soon, a faithful group of men began to follow Jesus and call him teacher. These men became His disciples. Jesus taught His disciples about the will of God and about the "new covenant" God will bring to humanity through Him. Jesus helped them to see that mankind is bound to the pain and futility of life as a result of sin. Due to sin, mankind lost its relationship with God. The purpose of this "new covenant" is to restore those who accept it into a renewed fellowship of forgiveness and love with God. Soon Jesus himself would pay for the sins of all humanity by being crucified unjustly on a Roman cross. Three days later, He would rise to life, having conquered death, to give hope to a hopeless world.And just as he thought with His disciples were witnesses to an amazing miracle. Their teacher, Jesus of Nazareth, died and three days later rose again to become their Messiah. Compelled by a great commission to share the love that the God of this universe had imparted upon them, the disciples began to proclaim this gospel of hope throughout the territory. Thus, from a small group of ordinary men that lived in a small province in Judea about 2000 years ago, the Christian church began, and the Christian Faith has then been spread throughout the world.
As it is Foretold by Prophecy:Though most of the historical record for the start of the Christian faith is recorded in the New Testament accounts, the history of Christianity actually began with prophecy in the Old Testament. There are over 300 prophecies (predictions) that span over a period of 1000 years that are recorded in the Old Testament concerning the coming of a Jewish Messiah. A study of Jesus' life, death and background will show that He was undoubtedly the fulfillment of these Messianic Prophecies. Thus long before Jesus walked the earth, His mission was made known to mankind through the Word of God.
