The New Testament tells us that Jesus is the Son of God, conceived in Mary, a descendant of Abraham and King David; the Messiah (anointed one) promised by God who would save his people from their sins.
May I suggest that you read “Who is Jesus?” here:

And ‘Jesus: God the Son or Son of God?’ here:

If you then have further questions, please ask.
I hope you find this helpful.
God bless,
