Answer:
The son of God the father. (of the Bible)
Step-by-step explanation:
According to the Christian faith, which based on the Bible, Jesus, also known as Jesus Christ or the Messiah was the son of God who came down to Earth as a human baby (birthed by the virgin Mary) to save humanity from death due to sin. There's ALOT I could talk about, but I'll try to keep it simple.
Sin, put very plainly, is anything that is anything that goes against the moral ideals of God. For example, lying, stealing, murder, adulatory, etc. I bet you could name more examples!
Anyways, because humans decided to sin when God created them, there was a death sentence put on humanity (because in the God's laws punishment for sin is death). But because of the grace of God (and because he loves humanity), he sent down his son, Jesus, to die in place on humanity so that if we repent and choose God, that death sentence is lifted. Jesus came back to life after three days. It's actually really beautiful.
