Jesus is the Reason for Christmas

Why did Jesus have to be born, live as one of us, die horribly, and be raised back to life?

 ⁶You see, at just the right time, when we were still powerless, Christ died for the ungodly. ⁷Very rarely will anyone die for a righteous man, though for a good man someone might possibly dare to die. ⁸But God demonstrates his own love for us in this: While we were still sinners, Christ died for us. - Romans 5:6-8
