Christianity is the world’s largest and most influential faith, with an estimated 2.2 billion adherents as of 2010.
For over two millennia, it has shaped civilizations, influenced laws, inspired art and literature, and transformed countless lives. At its core, Christianity is not just a set of beliefs but a relationship with Jesus Christ, who offers hope, redemption, and eternal life.
Whether you are a believer seeking to deepen your faith or someone exploring Christianity for the first time, understanding its foundations is essential.
The Origins of Christianity
Christianity originated in Jerusalem, in present-day Israel, and was founded by Jesus Christ Himself (Hebrews 12:2). Born in Bethlehem, Jesus was raised in Nazareth, fulfilling the prophecy that He would be called a “Nazarene.”
The Ministry of Jesus
At about 30 years old, Jesus began His public ministry. Before that, He spent 40 days and nights in the wilderness, fasting and overcoming temptation by the devil. Upon returning,
He preached repentance and the coming of God’s kingdom, gathering followers who believed He was the promised Messiah.
Jesus chose 12 disciples to accompany Him in His ministry throughout Judea, Samaria, and Galilee. He commissioned His followers to spread the Gospel to all nations (Matthew 28:19-20).
After three years of ministry, Jesus was crucified, died, and was buried. However, in fulfillment of prophecy, He rose from the dead three days later, appearing to His disciples and over 500 witnesses.
Forty days later, He ascended into heaven, promising to return (Acts 1:10-11).
The Bible: The Word of God
The Bible is the sacred text of Christianity, comprising both the Old Testament (Hebrew Scriptures) and the New Testament. It holds a central place in the Christian faith, regarded as the inspired and authoritative Word of God (2 Timothy 3:16).
Christians believe that the Bible was divinely inspired, meaning that God guided human authors to write His message.
The term “inspiration” means “God-breathed,” making the Bible unique among all other books. It provides wisdom, instruction, and revelation about God’s plan for humanity.
The Bible is not just a historical or religious document; it has been a transformative force in the world. It has shaped laws, ethics, and societies throughout history. The influence of the Bible extends into literature, art, and even science, with many of history’s greatest thinkers and leaders citing it as a source of inspiration.
Structure and Influence of the Bible
The Bible is composed of 66 books, written by more than 40 different authors over approximately 1,500 years.
Despite being written in different times, cultures, and languages, it carries a unified message of God’s redemptive plan.
The Old Testament contains prophecies and foreshadowings of the coming Messiah, while the New Testament reveals the fulfillment of those promises in Jesus Christ.
Today, the Bible remains the most widely distributed book in the world, available in over 700 languages, with portions translated into thousands more. It continues to be a source of faith, guidance, and transformation for millions of believers across the globe.

The Gospel: The Good News of Salvation
The word “Gospel” literally means “good news.” It is the message that God loves the world so much that He gave His only Son, Jesus Christ, to die for our sins so that we may have eternal life (John 3:16).
Understanding the Gospel Message
The apostle Paul summarizes the core elements of the Gospel in 1 Corinthians 15:3-6: Christ’s death, burial, resurrection, and post-resurrection appearances.
To fully appreciate the good news, we must first understand the bad news: we are all sinners, and our sins separate us from God (Romans 3:23; Isaiah 59:2). Since the fall of mankind in the Garden of Eden, sin has corrupted humanity, and only a perfect sacrifice could restore our relationship with God. Jesus, through His death on the cross, took upon Himself the punishment for our sins, satisfying God’s justice and offering salvation to all who believe in Him.
The Gospel is a message of hope, power, and salvation—available to everyone, Jew and Gentile alike. It is received by faith, transforming lives for eternity.
