Jesus Christ is real. Jesus Christ is God. God came to earth in the person of Jesus and lived as a man. He can fully identify and understand us because He lived among us. Because of mankind's sin, we were all separated from God. Jesus came as the only way of reconnecting us back to God our creator.
Today, mankind is living in a tragic condition due to sin. Someday soon Jesus is going to return to earth and deal with all mankind. Meanwhile, to everyone who will humble themselves and ask for His forgiveness, He will forgive and save for all eternity.
