Jesus during His ministry here on earth made statements that suggested and confirmed who He is; statements that pointed to Him as The Son of God, Some of these are:
“I and my Father are one.” (John 10:30).
“Believest thou not that I am IN THE FATHER, and the FATHER IN ME.? the words that I speak unto you I speak not of myself: but the Father that dwelleth in me, he doeth the works. Believe me that I am in the Father, and the Father in me: or else believe me for the very works’ sake.” (John 14:10-11).
“Holy Father, keep through thine own name those whom thou hast given me, that they may be one, as we are” (John 17:11).
“Neither pray I for these alone, but for them also which shall believe on me through their word; That they all may be ONE; as THOU, FATHER, ART IN ME, and I IN THEE, that they also may be ONE IN US: that the world may believe that thou hast sent me. And the glory which thou gavest me I have given them; that they may be ONE, even as WE ARE ONE” (John 17:20-22).
His reaction to those who see Him as blaspheming by making these claims:
“If he called them gods, unto whom the word of God came, and the scripture cannot be broken; Say ye of him, whom the Father hath sanctified, and sent into the world, Thou blasphemest; because I said, I am the Son of God? If I do not the works of my Father, believe me not” (John 10:35-37; see also John 11:4)
There were those who (like is prevalent today) Challenged His claim of being the Son of God:
“And the high priest arose, and said unto him, Answerest thou nothing? what is it which these witness against thee? But Jesus held his peace, And the high priest answered and said unto him, I adjure thee by the living God, that thou tell us whether thou be the Christ, the Son of God. Jesus saith unto him, Thou hast said: nevertheless I say unto you, Hereafter shall ye see the Son of man sitting on the right hand of power, and coming in the clouds of heaven” (Matthew 26:62-64; see also Matth. 27:40,43; Luke 22:70; John 19:7)
Even before He came into this world as a man (His incarnation), Prophet Daniel saw this:
“Then Nebuchadnezzar the king was astonished, and rose up in haste, and spake, and said unto his counsellors, Did not we cast three men bound into the midst of the fire? They answered and said unto the king, True, O king. He answered and said, Lo, I see four men loose, walking in the midst of the fire, and they have no hurt; and the form of the fourth is like the Son of God. Then Nebuchadnezzar came near to the mouth of the burning fiery furnace, and spake, and said, Shadrach, Meshach, and Abednego, ye servants of the most high God, come forth, and come hither. Then Shadrach, Meshach, and Abednego, came forth of the midst of the fire“ (Daniel 3:24-26).
The devil also acknowledged this in His bid to tempt Jesus before the start of His ministry:
“Then was Jesus led up of the Spirit into the wilderness to be tempted of the devil. And when he had fasted forty days and forty nights, he was afterward an hungered. And when the tempter came to him, he said, If thou be the Son of God, command that these stones be made bread” (Matthew 4:1-3, 6; see also Luke 4:3,9)
God the Father also confirmed these statements:
“Then answered Peter, and said unto Jesus, Lord, it is good for us to be here: if thou wilt, let us make here three tabernacles; one for thee, and one for Moses, and one for Elias. While he yet spake, behold, a bright cloud overshadowed them: and behold a voice out of the cloud, which said, This is my beloved Son, in whom I am well pleased; hear ye him. And when the disciples heard it, they fell on their face, and were sore afraid” (Matthew 17:4-6; see also Mark 9:6-8; Luke 9:34-36; 2 Peter 1:16-18).
Angel Gabriel confirmed to Jesus’ mother that her son would be the Son of God:
“Then said Mary unto the angel, How shall this be, seeing I know not a man? 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. And, behold, thy cousin Elisabeth, she hath also conceived a son in her old age: and this is the sixth month with her, who was called barren” (Luke 1:34-36).
Even the unclean spirits know that He is the Son of God:
“And when he was come to the other side into the country of the Gergesenes, there met him two possessed with devils, coming out of the tombs, exceeding fierce, so that no man might pass by that way. And, behold, they cried out, saying, What have we to do with thee, Jesus, thou Son of God? art thou come hither to torment us before the time? And there was a good way off from them an herd of many swine feeding” (Matthew 8:28-30; see also Mark 3:11; Luke 8:28).
The testimonies of those who were close to Him confirmed it:
“The beginning of the gospel of Jesus Christ, the Son of God; As it is written in the prophets, Behold, I send my messenger before thy face, which shall prepare thy way before thee. The voice of one crying in the wilderness, Prepare ye the way of the Lord, make his paths straight” (Mark 1:1-3; see also John 1:34, 49; 1 John 5:20).
The testimonies of those who came in contact with the power inherent in His being the Son of God:
“And when they were come into the ship, the wind ceased. Then they that were in the ship came and worshipped him, saying, Of a truth thou art the Son of God. And when they were gone over, they came into the land of Gennesaret” (Matthew 14:32-34; see also Luke 4:41; john 11:27).
Even at His death on the cross at Calvary, the centurion confirmed it:
“And came out of the graves after his resurrection, and went into the holy city, and appeared unto many. Now when the centurion, and they that were with him, watching Jesus, saw the earthquake, and those things that were done, they feared greatly, saying, Truly this was the Son of God. And many women were there beholding afar off, which followed Jesus from Galilee, ministering unto him” (Matthew 27:53-55; see also Mark 15:39).
The consequences of not believing in Him:
“For God sent not his Son into the world to condemn the world; but that the world through him might be saved. He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God. And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil” (John 3:17-19; see also 1 John 5:10,12).
