The main reason why I believe in Jesus Christ is because of this day – Resurrection Sunday. You see what separates Jesus from all other deities is not that He died (anyone can do that), but the fact that He rose. This is the day that proves Jesus is Lord!
(Below is taken from Mark 15 & 16)
Jesus Before Pilate
15 Very early in the morning, the chief priests, with the elders, the teachers of the law and the whole Sanhedrin, made their plans. So they bound Jesus, led him away and handed him over to Pilate.
2 “Are you the king of the Jews?” asked Pilate.
“You have said so,” Jesus replied.
3 The chief priests accused him of many things. 4 So again Pilate asked him, “Aren’t you going to answer? See how many things they are accusing you of.”
5 But Jesus still made no reply, and Pilate was amazed.
9 “Do you want me to release to you the king of the Jews?” asked Pilate, 10 knowing it was out of self-interest that the chief priests had handed Jesus over to him. 11 But the chief priests stirred up the crowd to have Pilate release Barabbas instead.
12 “What shall I do, then, with the one you call the king of the Jews?” Pilate asked them.
13 “Crucify him!” they shouted.
14 “Why? What crime has he committed?” asked Pilate.
But they shouted all the louder, “Crucify him!”
15 Wanting to satisfy the crowd, Pilate released Barabbas to them. He had Jesus flogged, and handed him over to be crucified.
The Crucifixion of Jesus
25 It was nine in the morning when they crucified him. 26 The written notice of the charge against him read: the king of the jews.
27 They crucified two rebels with him, one on his right and one on his left.  [a] 29 Those who passed by hurled insults at him, shaking their heads and saying, “So! You who are going to destroy the temple and build it in three days, 30 come down from the cross and save yourself!” 31 In the same way the chief priests and the teachers of the law mocked him among themselves. “He saved others,” they said, “but he can’t save himself! 32 Let this Messiah, this king of Israel, come down now from the cross, that we may see and believe.” Those crucified with him also heaped insults on him.
The Burial of Jesus
42 It was Preparation Day (that is, the day before the Sabbath). 44 Pilate was surprised to hear that he was already dead. Summoning the centurion, he asked him if Jesus had already died. 45 When he learned from the centurion that it was so, he gave the body to Joseph. 46 So Joseph bought some linen cloth, took down the body, wrapped it in the linen, and placed it in a tomb cut out of rock. Then he rolled a stone against the entrance of the tomb. 47 Mary Magdalene and Mary the mother of Joseph saw where he was laid.
(Below is taken from Luke 24) –
Jesus Has Risen
On the first day of the week, very early in the morning, the women took the spices they had prepared and went to the tomb. 2 They found the stone rolled away from the tomb, 3 but when they entered, they did not find the body of the Lord Jesus. 4 While they were wondering about this, suddenly two men in clothes that gleamed like lightning stood beside them. 5 In their fright the women bowed down with their faces to the ground, but the men said to them, “Why do you look for the living among the dead? 6 He is not here; he has risen! Remember how he told you, while he was still with you in Galilee: 7 ‘The Son of Man must be delivered over to the hands of sinners, be crucified and on the third day be raised again.’
Jesus Appears to the Disciples
36 While they were still talking about this, Jesus himself stood among them and said to them, “Peace be with you.”
37 They were startled and frightened, thinking they saw a ghost. 38 He said to them, “Why are you troubled, and why do doubts rise in your minds? 39 Look at my hands and my feet. It is I myself! Touch me and see; a ghost does not have flesh and bones, as you see I have.”
44 He said to them, “This is what I told you while I was still with you: Everything must be fulfilled that is written about me in the Law of Moses, the Prophets and the Psalms.”
45 Then he opened their minds so they could understand the Scriptures. 46 He told them, “This is what is written: The Messiah will suffer and rise from the dead on the third day, 47 and repentance for the forgiveness of sins will be preached in his name to all nations
