Jesus' life is a historical record and its historicity is hardly ever questioned. "The Word became flesh, and dwelt among us, and we saw His glory" (Jn 1:14). One day Jesus "asked his disciples, 'Who do you say I am?'" (Mt 16:15). Even "the scribes and Pharisees said to Him, 'Teacher'" (12:38). But "Peter responded, 'You are the Christ'" (16:16). "No one can say, 'Jesus is Lord,' except by the Holy Spirit" (Ro 10:9). "Every tongue will confess that Jesus As Lord" (Php 2:11). "Whoever will call on the name of the Lord will be saved" (Ro 10:13).
Fulfilled prophecy from the Bible establishes who Jesus is. He initiated and witnessed it saying, "'I am sending you prophets and wise men and scribes'" (Mt 23:34). It pointed towards his purpose and he said, "'Was it not necessary for the Christ to suffer these things and to enter into His glory?'" (Lk 24:26). He said the scriptures "'testify about Me'" (Jn 5:39) and "'all this has taken place to fulfill the Scriptures of the prophets" (Mt 26:56). But they were "'slow of heart to believe in all that the prophets have spoken!'" (Lk 24:25) so "He explained to them the things concerning Himself in all the Scriptures" (:27).
At a certain time "Jesus began to show His disciples that He must go to Jerusalem, and suffer many things from the elders and chief priests and scribes, and be killed, and raised up the third day" (Mt 16:21). He then explained, "'Destroy this temple, and in three days I will raise it up'" (Jn 2:19). The Jews then wanted a sign and Jesus responded, "'Just as Jonah was three days and three nights in the belly of the sea monster, so will the Son of Man be three days and three nights in the heart of the earth'" (Mt 13:40).
When Luke wrote his gospel he cited that "many have undertaken to compile an account . . . and they were handed down to us by those who from the beginning were eyewitnesses" (Lk1:1-2). He "investigated everything carefully" (:3) in order "that you may know the exact truth" (:4). After the resurrection "He appeared to Cephas, then to the twelve" (1Co 15:5). "When the doors were shut where the disciples were, for fear of the Jews, Jesus came and stood in their midst and said to them, 'Peace be with you'" (Jn 20:19). "He also presented Himself alive after His suffering, by many convincing proofs, appearing to more than five hundred brethren at one time, most of whom remain until now" (1Co 15:6). He visited with two disciples and when he ate with them "their eyes were opened and they recognized Him . . . [and said] 'were not our hearts burning within us while He was speaking to us on the road, while He was explaining the Scriptures to us?'" (Lk 24:31-32). There was a "third time that Jesus was manifested to the disciples" (Jn 21:14). "When the day was now breaking, Jesus stood on the beach; yet the disciples did not know that it was Jesus" (:4). Then John "said to Peter, 'It is the Lord'" (:7). He met them on the beach but "none of the disciples ventured to question Him, 'Who are You?' knowing that it was the Lord" (:12).
