In these various sermons, the Lord is referred to by several different titles. For instance, He is called the Lord, Lord God, God, Jesus, Mary's Baby, and the Lamb. According to the New Testament, Jesus was born on earth as a baby. His mother, Mary, was a virgin impregnated by the power of God. Jesus lived 33 years on earth. During this time he preached to the general public and taught in more detail to a small band of disciples. Jesus was crucified as a result of his claim that he was the Son of God. According to the Bible, it is this death on the cross that allows the entirety of mankind to have the opportunity to receive salvation.
