"A saving knowledge of Christ crucified and risen is not the mere result of right reasoning about historical facts. It is the result of spiritual illumination to see those facts for what they really are: a revelation of the truth and glory of God in the face of Christ — who is the same yesterday today and forever."
Please read Eight Reasons I Believe that Jesus Rose from the Dead, by John Piper, Desiring God, at One Place.
Jesus himself testified to His coming resurrection from the dead:
And He began to teach them that the Son of Man must suffer many things and be rejected by the elders and the chief priests and the scribes, and be killed, and after three days rise again.
And while they were gathering together in Galilee, Jesus said to them, "The Son of Man is going to be delivered into the hands of men;"
saying, "The Son of Man must suffer many things and be rejected by the elders and chief priests and scribes, and be killed and be raised up on the third day."
Jesus answered them, "Destroy this temple, and in three days I will raise it up."
"We heard Him say, 'I will destroy this temple made with hands, and in three days I will build another made without hands.'"
and said, "This man stated, 'I am able to destroy the temple of God and to rebuild it in three days.'"
But He answered and said to them, "An evil and adulterous generation craves for a sign; and yet no sign will be given to it but the sign of Jonah the prophet;
"An evil and adulterous generation seeks after a sign; and a sign will not be given it, except the sign of Jonah." And He left them and went away.
Jesus said to them, "Did you never read in the Scriptures, 'THE STONE WHICH THE BUILDERS REJECTED, THIS BECAME THE CHIEF CORNER stone; THIS CAME ABOUT FROM THE LORD, AND IT IS MARVELOUS IN OUR EYES'?
and said, "Sir, we remember that when He was still alive that deceiver said, 'After three days I am to rise again.'
The tomb was empty on Easter:
but when they entered, they did not find the body of the Lord Jesus.
Now while they were on their way, some of the guard came into the city and reported to the chief priests all that had happened. 12 And when they had assembled with the elders and consulted together, they gave a large sum of money to the soldiers, and said, "You are to say, 'His disciples came by night and stole Him away while we were asleep.' "And if this should come to the governor's ears, we will win him over and keep you out of trouble." And they took the money and did as they had been instructed; and this story was widely spread among the Jews, and is to this day.
The disciples were almost immediately transformed from men who were hopeless and fearful after the crucifixion into men who were confident and bold witnesses of the resurrection:
"But we were hoping that it was He who was going to redeem Israel. Indeed, besides all this, it is the third day since these things happened."
So when it was evening on that day, the first day of the week, and 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."
But God raised Him up again, putting an end to the agony of death, since it was impossible for Him to be held in its power.
but put to death the Prince of life, the one whom God raised from the dead, a fact to which we are witnesses.
being greatly disturbed because they were teaching the people and proclaiming in Jesus the resurrection from the dead.
This Jesus God raised up again, to which we are all witnesses.
But they did not understand this statement, and they were afraid to ask Him.
But these words appeared to them as nonsense, and they would not believe them.
So the other disciple who had first come to the tomb then also entered, and he saw and believed. For as yet they did not understand the Scripture, that He must rise again from the dead.
Paul claimed that, not only had he seen the risen Christ, but that 500 others had seen him also, and many were still alive when he made this public claim:
After that He appeared to more than five hundred brethren at one time, most of whom remain until now, but some have fallen asleep;
1 Corinthians 15:6
The sheer existence of a thriving, empire-conquering early Christian church supports the truth of the resurrection claim:
"Therefore let all the house of Israel know for certain that God has made Him both Lord and Christ - this Jesus whom you crucified."
The Apostle Paul's conversion supports the truth of the resurrection:
For I would have you know, brethren, that the gospel which was preached by me is not according to man. For I neither received it from man, nor was I taught it, but I received it through a revelation of Jesus Christ. For you have heard of my former manner of life in Judaism, how I used to persecute the church of God beyond measure and tried to destroy it; and I was advancing in Judaism beyond many of my contemporaries among my countrymen, being more extremely zealous for my ancestral traditions. But when God, who had set me apart even from my mother's womb and called me through His grace, was pleased to reveal His Son in me so that I might preach Him among the Gentiles, I did not immediately consult with flesh and blood, nor did I go up to Jerusalem to those who were apostles before me; but I went away to Arabia, and returned once more to Damascus.
Now Saul, still breathing threats and murder against the disciples of the Lord, went to the high priest,
but their plot became known to Saul. They were also watching the gates day and night so that they might put him to death; but his disciples took him by night and let him down through an opening in the wall, lowering him in a large basket.
"And I said, 'Who are You, Lord?' And the Lord said, 'I am Jesus whom you are persecuting. 'But get up and stand on your feet; for this purpose I have appeared to you, to appoint you a minister and a witness not only to the things which you have seen, but also to the things in which I will appear to you; rescuing you from the Jewish people and from the Gentiles, to whom I am sending you, to open their eyes so that they may turn from darkness to light and from the dominion of Satan to God, that they may receive forgiveness of sins and an inheritance among those who have been sanctified by faith in Me.'
The New Testament witnesses do not bear the stamp of dupes or deceivers:
"And why do you not even on your own initiative judge what is right?"
There is a self-authenticating glory in the gospel of Christ's death and resurrection as narrated by the biblical witnesses:
"But when He, the Spirit of truth, comes, He will guide you into all the truth; for He will not speak on His own initiative, but whatever He hears, He will speak; and He will disclose to you what is to come.
in whose case the god of this world has blinded the minds of the unbelieving so that they might not see the light of the gospel of the glory of Christ, who is the image of God.
2 Corinthians 4:4
For God, who said, "Light shall shine out of darkness," is the One who has shone in our hearts to give the Light of the knowledge of the glory of God in the face of Christ.
2 Corinthians 4:6
