Who is Jesus?
Jesus is God. About two thousand years ago, Jesus left Heaven, came to Earth, and took on the form of man. He did this because man had sinned causing a division between man and God. The consequences for man’s sin would be Hell, the Lake of Fire, and eternal separation from God. Man could not and cannot save himself. This is why Jesus is often called Savior. He came to save man from the consequences of his sin.
Even though Jesus lived a perfect life, He died for sin (our sin). He died in our place. He died so we could live. Even though they buried Him, He rose again conquering death. He now offers us eternal life and life to the full (with purpose, value, and meaning) if we turn from ourselves and follow Him. This is why Jesus is often called Lord. Becoming a Christian involves faith. It is turning from serving ourselves to following Jesus and living life for Him.
"If you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved." “For ‘everyone who calls on the name of the Lord will be saved.'"
(Romans 10:9, 13)
