Christianity
Christianity is one of the major world religions and as of 2010, it is by far the largest religion with an estimated 2.2 billion adherents worldwide. It is the predominant religion in the west for many centuries and it remains the majority religion of Europe and the Americas.
Christianity originated in Jerusalem in present-day Israel. It was founded by no other than Jesus Christ Himself (Hebrews 12:2). Jesus Christ was born in the small town of Bethlehem, a few miles away from Jerusalem. He was raised in the town of Nazareth in the region of Galilee in fulfillment of the prophecy that He would be called a “Nazarene”
Jesus started His ministry when He was about 30 years old. But in order to prepare Himself for His ministry, Jesus went into the wilderness where He fasted for 40 days and 40 nights, was tempted by the devil but was able to overcome. Upon His return, many people who believed Him to be the Messiah gathered in a group to listen to Him.
Jesus then chose for Himself 12 disciples/apostles and they wandered through Judea, Samaria and Galilee preaching repentance for the kingdom of God is at hand (Matthew 4:17). Jesus commissioned His followers to preach the Gospel into all the world (Matthew 28:19-20).
After barely 3 years of Jesus’ ministry, He was crucified, died and was buried. But three days later, according to prophecy, He rose again from the dead. He appeared to His disciples and to more than 500 people on several occasions. Forty days later He ascended visibly and bodily into heaven (Acts 1:10-11).
The Bible 
The sacred text of Christianity is the Bible, including both the Hebrew scriptures (also known as the Old Testament) and the New Testament. The Bible has always occupied the central place in the Christian faith.
From the time of the writing of the first books of the Old Testament in the days of Moses until modern times the Holy Scriptures have been regarded by all Christian theologians as the unique and incomparable Word of God. Christians believe the Bible to be the inspired word of God (2 Timothy 3:16).
When people speak of the Bible as inspired, they are referring to the fact that God divinely influenced the human authors of the Scriptures in such a way that what they wrote was the very Word of God. In the context of the Scriptures, the word “inspiration” simply means “God-breathed.” Inspiration means the Bible truly is the Word of God and makes the Bible unique among all other books.
Though there has been some debate on the meaning of the phrase “all scripture,” the preceding verse referring as it does to “the holy scriptures,” gives us an important lead. It makes plain that verse 16 is not referring to all writings, but rather to those regarded as the Word of God, such as the Old Testament Scriptures and those portions of the New Testament which had been written at that time. Such Scriptures are declared to be given by inspiration of God.
The Gospel
So what is the gospel? The gospel which literally means “good news” is that God loves the world so much that He gave His only begotten Son to die for our sins (John 3:16). The Gospel of Jesus Christ is the power of God to salvation for everyone who believes (Romans 1:16). The apostle Paul summarizes the most basic elements of the gospel in 1 Corinthians 15:3-6 and these are the death, burial, resurrection and appearances of the resurrected Christ.
In order for us to truly understand the gospel as the good news, we must first understand the bad news. The bad news is that we are all sinners and our sins have separated us from God (Romans 3:23 & Isaiah 59:2). As a result of the fall of man in the Garden of Eden, everyone of us has been corrupted by sin and the only way our relationship with God is restored is if somebody will pay for our sins.
That’s what Jesus came to do. He took upon Himself the sin of the world to give God justice.
The gospel is a powerful message, it is a saving message; a universal message to both the Jews and Gentiles and is received by faith.
May the good Lord richly bless you!
In Christ,
