John 20:29 (ESV)
29 Jesus said to him, “Have you believed because you have seen me? Blessed are those who have not seen and yet have believed.”
Jesus appears to be saying that those who believe without seeing are especially blessed. However, the Apostle Paul saw many things, and still was blessed:
2 Corinthians 12:1-10 (ESV)
2 I must go on boasting. Though there is nothing to be gained by it, I will go on to visions and revelations of the Lord. 2 I know a man in Christ who fourteen years ago was caught up to the third heaven—whether in the body or out of the body I do not know, God knows. 3 And I know that this man was caught up into paradise—whether in the body or out of the body I do not know, God knows— 4 and he heard things that cannot be told, which man may not utter. 5 On behalf of this man I will boast, but on my own behalf I will not boast, except of my weaknesses— 6 though if I should wish to boast, I would not be a fool, for I would be speaking the truth; but I refrain from it, so that no one may think more of me than he sees in me or hears from me. 7 So to keep me from becoming conceited because of the surpassing greatness of the revelations, a thorn was given me in the flesh, a messenger of Satan to harass me, to keep me from becoming conceited. 8 Three times I pleaded with the Lord about this, that it should leave me. 9 But he said to me, “My grace is sufficient for you, for my power is made perfect in weakness.” Therefore I will boast all the more gladly of my weaknesses, so that the power of Christ may rest upon me. 10 For the sake of Christ, then, I am content with weaknesses, insults, hardships, persecutions, and calamities. For when I am weak, then I am strong.
2 Timothy 4:6-8 (ESV)
6 For I am already being poured out as a drink offering, and the time of my departure has come. 7 I have fought the good fight, I have finished the race, I have kept the faith. 8 Henceforth there is laid up for me the crown of righteousness, which the Lord, the righteous judge, will award to me on that day, and not only to me but also to all who have loved his appearing.
If those who believe without seeing are especially blessed, then how come the Apostle Paul had so many extraordinary revelations from the Lord and still was blessed?
