Quite often I encounter those who are involved in cults who pose the question, "How can Jesus be both God and Son of God?" One should be reminded that Jesus referred to Himself as "Son of God" and "Son of man." The designation "Son of God" refers to the deity of Christ and "Son of man" refers to the humanity of Christ.
Phil. 2:5-8 tells us that Jesus, "being in the form of God, thought it not robbery to be equal with God" and yet He "made himself of no reputation, and took upon Him the form of a servant, and was made in the likeness of men: And being found in fashion as a man..." Those verses show that Jesus was equal with God, yet humbled Himself and took the form of a servant.
Look at John 5:18 and see that the Jews wanted to kill Jesus "because He not only had broken the Sabbath, but said also that God was His Father, making Himself equal with God." John 10:30-33 states, "I and the Father are one. Then the Jews took up stones again to stone Him. Jesus answered them, Many good works have I shewed you from my Father; for which of those works do ye stone me? The Jews answered Him, saying, For a good work we stone thee not; but for blasphemy; and because that thou, being a man, makest thyself God."
Isa. 7:14 states, "Therefore the Lord Himself shall give you a sign; Behold a virgin shall conceive, and bear a son, and shall call His name Immanuel." Matthew 1:23 repeats, "Behold, a virgin shall be with child, and shall bring forth a son, and they shall call His name Emmanuel, which being interpreted is, God with us."
2 Cor. 5:19 states, "To wit, that God was in Christ, reconciling the world unto Himself..." Col. 1:15-19 reveals Christ as "the image of the invisible God..." Philip asked Jesus in John 14:8, "Lord, shew us the Father, and it sufficeth us." Jesus answered in v.9, "Have I been so long with you, and yet hast thou not known me, Philip? He that hath seen me hath seen the Father; and how sayest thou Shew us the Father." Isa. 9:6 says, "For unto us a child is born (humanity of Christ), unto us a Son is given (deity of Christ): and the government shall be upon His shoulder: and His name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace." 1 Tim.3:16 tells us, "And without controversy great is the mystery of godliness: God was manifest in the flesh, justified in the Spirit, seen of angels, preached unto the Gentiles, believed on in the world, received up into glory."
Jesus is the Son of God in reference to His entrance into the world in a body of flesh. Luke 1:35 states, "And the angel answered and said unto her, The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called the Son of God."
Have you been born again through faith in the Son of God who is God the Son?
