Can we be sure that Jesus rose from the dead? Yes!! There are many infallible proofs of his resurrection!
(Acts 1:3) To whom also he showed himself alive after his passion by many infallible proofs, being seen of them forty days, and speaking of the things pertaining to the kingdom of God:
Here are the chronological eyewitness accounts of the bodily appearance of Jesus Christ following his resurrection.
Mary Magdalene, Mary, the mother of James, Salome, Joanna, and at least one other woman with them
(Mat 28:1) 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.
(Mark 16:1) 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.
(Luke 24:10) 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.
(Mark 16:5-6) 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. 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.
(Luke 24:4-5) And it came to pass, as they were much perplexed thereabout, behold, two men stood by them in shining garments: 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?
Peter and John
(John 20:2-3) 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. Peter therefore went forth, and that other disciple, and came to the sepulchre.
Mary Magdalene alone
(John 20:15-17) Jesus saith unto her, Woman, why weepest thou? whom seekest thou? She, supposing him to be the gardener, saith unto him, Sir, if thou have borne him hence, tell me where thou hast laid him, and I will take him away. Jesus saith unto her, Mary. She turned herself, and saith unto him, Rabboni; which is to say, Master. Jesus saith unto her, Touch me not; for I am not yet ascended to my Father: but go to my brethren, and say unto them, I ascend unto my Father, and your Father; and to my God, and your God.
Mary and other women on the way to tell the disciples
(Mat 28:8-9) And they departed quickly from the sepulchre with fear and great joy; and did run to bring his disciples word. And as they went to tell his disciples, behold, Jesus met them, saying, All hail. And they came and held him by the feet, and worshipped him.
Cleopas and another man on the road to Emmaus
(Luke 24:13-15) And, behold, two of them went that same day to a village called Emmaus, which was from Jerusalem about threescore furlongs. And they talked together of all these things which had happened. And it came to pass, that, while they communed together and reasoned, Jesus himself drew near, and went with them. (Luke 24:18) And the one of them, whose name was Cleopas, answering said unto him, Art thou only a stranger in Jerusalem, and hast not known the things which are come to pass there in these days?
The disciples and them that were with them
(Luke 24:33) And they rose up the same hour, and returned to Jerusalem, and found the eleven gathered together, and them that were with them, (Luke 24:36-40) And as they thus spake, Jesus himself stood in the midst of them, and saith unto them, Peace be unto you. But they were terrified and affrighted, and supposed that they had seen a spirit. And he said unto them, Why are ye troubled? and why do thoughts arise in your hearts? Behold my hands and my feet, that it is I myself: handle me, and see; for a spirit hath not flesh and bones, as ye see me have. And when he had thus spoken, he showed them his hands and his feet.
The disciples and Thomas, eight days later
(John 20:26) And after eight days again his disciples were within, and Thomas with them: then came Jesus, the doors being shut, and stood in the midst, and said, Peace be unto you.
More than 500 brethren at once
(1 Cor 15:6) After that, he was seen of above five hundred brethren at once; of whom the greater part remain unto this present, but some are fallen asleep.
The disciples while they were fishing
(John 21:1-14) After these things Jesus showed himself again to the disciples at the sea of Tiberias; and on this wise showed he himself.
(1 Cor 15:8) And last of all he was seen of me also, as of one born out of due time.
The disciples and others at his ascension
(Acts 1:9) And when he had spoken these things, while they beheld, he was taken up; and a cloud received him out of their sight.
John at the Revelation
(Rev 1:12-13) And I turned to see the voice that spake with me. And being turned, I saw seven golden candlesticks; And in the midst of the seven candlesticks one like unto the Son of man, clothed with a garment down to the foot, and girt about the paps with a golden girdle. (Rev 1:18) I am he that liveth, and was dead; and, behold, I am alive for evermore, Amen; and have the keys of hell and of death.
