Jesus lived as a spirit person in heaven before he was born in Bethlehem. He was God’s first creation and the only one created directly by God. Therefore, he is fittingly referred to as God’s only-begotten Son. In heaven, he often spoke as God’s representative. That is why he is called the Word. He also acted as God’s helper and took part in the creation of all other things. (John 1:2, 3, 14) Jesus lived with God in heaven for aeons before humankind was created.​—Read Micah 5:2; John 17:5.

Jehovah transferred the life of Jesus from heaven to the womb of Mary by means of holy spirit. So Jesus was born without the aid of a human father. Angels announced his birth to some local shepherds, who were living outdoors at night as they kept watch over their flocks. (Luke 2:8-12) Thus, Jesus was born, not in the depths of winter, but likely in early October, when the weather was still warm. Some time later, Mary and her husband, Joseph, took Jesus to their home in Nazareth and raised him there. Joseph cared for Jesus as his adopted son.​—Read Matthew 1:18-23.

When Jesus was about 30 years old, he was baptized, and God publicly announced that Jesus was his Son. Then Jesus began the work that God had sent him to do.​—Read Matthew 3:16, 17.

God sent Jesus to teach people the truth. Jesus taught about God’s Kingdom, a government in heaven that will bring peace to all the earth. He provided the hope of everlasting life. (John 4:14; 18:36, 37) Jesus also taught people many things about finding real happiness. (Matthew 5:3; 6:19-21) He taught by example. For instance, he showed how to do God’s will even in difficult circumstances. When he was mistreated, he did not retaliate.​—Read 1 Peter 2:21-24.

Jesus taught his followers self-sacrificing love. He had enjoyed many privileges living in heaven with his Father, yet he humbly obeyed his Father and came to earth to live among mankind. No one could give us a finer example of love than Jesus.​—Read John 15:12, 13; Philippians 2:5-8.

God also sent Jesus to die for our sins. (John 3:16) We are all sinners, meaning that we are imperfect and sinful. That is why we get sick and die. In contrast, the first man, Adam, was perfect. He had no sin and would never have died or become sick. But he lost his perfection when he disobeyed God. From Adam, we inherited sin and its wages, death.​—Read Romans 5:12; 6:23.

Jesus, who was a perfect man, did not die for his own sins. He died for our sins. Jesus’ death makes it possible for us to enjoy everlasting life and be blessed by God.​—Read 1 Peter 3:18.
