Alex said "Why did Yahshua said that you will never see me again until you learn to say bless is he who comes in the name of the Lord?"
Is it the following verse you're referring to?
Luk 13:35 KJV
(35) Behold, your house is left unto you desolate: and verily I say unto you, Ye shall not see me, until the time come when ye shall say, Blessed is he that cometh in the name of the Lord.
You are taking the verse out of context; Yeshua was speaking to the house of Judah who rejected Him as HaMeshiach. They would not "see" Him or recognize Him until the last days, shortly before His final return.
Zec 12:10 KJV
(10) And I will pour upon the house of David, and upon the inhabitants of Jerusalem, the spirit of grace and of supplications: and they shall look upon me whom they have pierced, and they shall mourn for him, as one mourneth for his only son, and shall be in bitterness for him, as one that is in bitterness for his firstborn.
Rev 1:7 KJV
(7) Behold, he cometh with clouds; and every eye shall see him, and they also which pierced him: and all kindreds of the earth shall wail because of him. Even so, Amen.
When He is seen once again coming with the clouds, the House of Judah and the House of Israel will have been reconciled and made ready as one bride for the coming of the bridegroom and will hence, see Him again and Bless Him as coming in the Name of the Lord.
Your statement/question is incorrect in it's assertion. Not all will have died before being raised to meet Him. Those that have died in Him will be the first to rise and be resurrected "The dead in Christ shall rise first:" and those who are still alive at His coming will follow afterwards in the twinkling of an eye.
1Th 4:16 KJV
(16) For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:
1Co 15:52 KJV
(52) In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
Again Alex, if you would please provide scripture for you questions or conclusions it would help greatly.
