Why Jesus came to be born on Earth?
To understand the reason for His birth, we must focus on a truth that should trouble us. This truth is that ALL are sinners because we have broken the Law of God every day of our lives. Some despite this some people consider themselves "good people", but the truth is that nobody is good, not even one (Ro.3: 12). We have all sinned against God. How many lies you said in your life? Have you ever stole something even if it was insignificant? Have you ever watched someone to sexually desire in your heart? Have you ever used the name of God in vain? These are only 4 of the 10 commandments of God we have not obey.
We have all sinned and therefore is the just condemnation in a place the Bible calls Hell. Yes, dying face trial before God, Righteous Judge, who will judge with justice and will not acquit the guilty (Nm.14: 18). Well, these are very bad news and it is more likely that this biblical truth you are uncomfortable. We will all die to address this.
What about Christmas then? The angels said :: "is born a Savior who is Christ the Lord" (Luke 2: 10-11). Indeed God does not want the sinner's death. He has extended His great mercy sent His Son Jesus Christ as the Messiah Savior. The Bible says "For God so loved the world that He gave His only begotten Son, that whosoever believeth in Him should NOT PERISH BUT HAVE ETERNAL LIFE" (John 3:16). The Good News is that Jesus Christ became man, living among us without reference to sin, but were imputed ALL the sins of ALL of us (Isaiah 53: 6). Suffers our punishment and died our death being nailed to a cross under the wrath of God Almighty, anger and punishment we deserved to us. Now His perfect Blood invaluable wash us from ALL sin. The death of Christ on the cross fully satisfied the justice of God. Now we can be forgiven and God remains Righteous.
