Even if you say that there was no Jesus you are wrong.... despite if you believe that He did miracles... there was a guy called Jesus, who was crucified. This guy obviously did believe He was the Son of God.... and I don't know a single person who would go through this pain for anyone....... Therefore it makes sense that He surely was the son of God!....
Mark 15:33- 41
The Death of Jesus33 At noon, darkness came over the whole land until three in the afternoon.34 And at three in the afternoon Jesus cried out in a loud voice, "Eloi, Eloi, lema sabachthani?" (which means "My God, my God, why have you forsaken me?").t
35 When some of those standing near heard this, they said, "Listen, he's calling Elijah."
36 Someone ran, filled a sponge with wine vinegar, put it on a staff, and offered it to Jesus to drink. "Now leave him alone. Let's see if Elijah comes to take him down," he said.
37 With a loud cry, Jesus breathed his last.
38 The curtain of the temple was torn in two from top to bottom.39 And when the centurion, who stood there in front of Jesus, saw how he died, he said, "Surely this man was the Son of God!"
40 Some women were watching from a distance. Among them were Mary Magdalene, Mary the mother of James the younger and of Joseph,t and Salome.41 In Galilee these women had followed him and cared for his needs. Many other women who had come up with him to Jerusalem were also there.
Seriously, how could you not love Him?
