Who is Jesus?
Jesus Christ is the one and only, eternal Son of God. He was conceived of the Holy Spirit and born of the virgin Mary.
As the Son of God He perfectly reveals to humankind what God is like: His mercy, grace, love, justice, righteousness, wisdom and much more. He is also the only one to ever live perfectly doing the will of God. Part of which was to die on the cross and in doing so make a way for humankind to be saved from sin.
Thankfully He did not stay dead but rather God raised Jesus from the dead and with a glorified body Jesus appeared to His disciples; sometimes just one of them, sometimes all the disciples together and at another time to a crowd. After forty days He ascended into heaven and is now at the right hand of God.
