The whole premise of Christianity is the fact that Jesus is Risen. Yes, Jesus' birth is very important and so is his death, but his resurrection is paramount. This was the reason He came to Earth. He came to set the captives free; free from sin and death. In his death all sin was paid for on the Cross of Calvary. If not for the fact that He died and ultimately rose from the dead, his whole life would have been in vain. Jesus' death and resurrection also represents our lives when we trust in Him. We die to sin and death and are resurrected through the blood of Jesus Christ. This was shadowed by the blood on the doorway when the Angel of Death passed over the Egypt killing all the first born. Everyone that had the blood over their doorpost was spared. This what the blood of Jesus Christ represents. When we accept Jesus Christ as our Lord and Savior we have the blood of Jesus covering us. We are free from the curse of sin and eternal death. The promise Jesus gave us is eternal life and victory over death.
Passage Matthew 28:1-7:
1 In the end of the sabbath, as it began to dawn toward the first day of the week, came Mary Magdalene and the other Mary to see the sepulchre.
2 And, behold, there was a great earthquake: for the angel of the Lord descended from heaven, and came and rolled back the stone from the door, and sat upon it.
3 His countenance was like lightning, and his raiment white as snow:
4 And for fear of him the keepers did shake, and became as dead men.
5 And the angel answered and said unto the women, Fear not ye: for I know that ye seek Jesus, which was crucified.
6 He is not here: for he is risen, as he said. Come, see the place where the Lord lay.
7 And go quickly, and tell his disciples that he is risen from the dead; and, behold, he goeth before you into Galilee; there shall ye see him: lo, I have told you.
Passage Mark 16:1-8:
1 And when the sabbath was past, Mary Magdalene, and Mary the mother of James, and Salome, had bought sweet spices, that they might come and anoint him.
2 And very early in the morning the first day of the week, they came unto the sepulchre at the rising of the sun.
3 And they said among themselves, Who shall roll us away the stone from the door of the sepulchre?
4 And when they looked, they saw that the stone was rolled away: for it was very great.
5 And entering into the sepulchre, they saw a young man sitting on the right side, clothed in a long white garment; and they were affrighted.
6 And he saith unto them, Be not affrighted: Ye seek Jesus of Nazareth, which was crucified: he is risen; he is not here: behold the place where they laid him.
7 But go your way, tell his disciples and Peter that he goeth before you into Galilee: there shall ye see him, as he said unto you.
8 And they went out quickly, and fled from the sepulchre; for they trembled and were amazed: neither said they any thing to any man; for they were afraid.
Passage Luke 24:1-12:
1 Now upon the first day of the week, very early in the morning, they came unto the sepulchre, bringing the spices which they had prepared, and certain others with them.
2 And they found the stone rolled away from the sepulchre.
3 And they entered in, and found not the body of the Lord Jesus.
4 And it came to pass, as they were much perplexed thereabout, behold, two men stood by them in shining garments:
5 And as they were afraid, and bowed down their faces to the earth, they said unto them, Why seek ye the living among the dead?
6 He is not here, but is risen: remember how he spake unto you when he was yet in Galilee,
7 Saying, The Son of man must be delivered into the hands of sinful men, and be crucified, and the third day rise again.
8 And they remembered his words,
9And returned from the sepulchre, and told all these things unto the eleven, and to all the rest.
10 It was Mary Magdalene and Joanna, and Mary the mother of James, and other women that were with them, which told these things unto the apostles.
11 And their words seemed to them as idle tales, and they believed them not.
12 Then arose Peter, and ran unto the sepulchre; and stooping down, he beheld the linen clothes laid by themselves, and departed, wondering in himself at that which was come to pass
Passage John 20:1-9:
1 The first day of the week cometh Mary Magdalene early, when it was yet dark, unto the sepulchre, and seeth the stone taken away from the sepulchre.
2 Then she runneth, and cometh to Simon Peter, and to the other disciple, whom Jesus loved, and saith unto them, They have taken away the LORD out of the sepulchre, and we know not where they have laid him.
3 Peter therefore went forth, and that other disciple, and came to the sepulchre.
4 So they ran both together: and the other disciple did outrun Peter, and came first to the sepulchre.
5 And he stooping down, and looking in, saw the linen clothes lying; yet went he not in.
6 Then cometh Simon Peter following him, and went into the sepulchre, and seeth the linen clothes lie,
7 And the napkin, that was about his head, not lying with the linen clothes, but wrapped together in a place by itself.
8 Then went in also that other disciple, which came first to the sepulchre, and he saw, and believed.
9 For as yet they knew not the scripture, that he must rise again from the dead.
