I will try and answer in my own inadequate way using Bible scripture as my guide. I'm going to treat your post as a serious question for now. If I'm only feeding the trolls, then I expect I'll not be back.
So man will become Gods?, know all that it is possible to know,
Be omnipotent, eventually?
Well, lose the captial G and then you are on to something.
Jesus quoted the psalms when he said in John 10:34 "Jesus answered them, "Is it not written in your Law, 'I have said you are gods'"
Looking at the context of John 10, and then reading Psalm 82 which Jesus quoted, leads me to believe that God created us with great capability. Our sin and subsequent separation from God has placed us in a greatly lowered estate than what is eventually planned for us.
But, will we become omniscient? Will we become like God with infinite awareness, understanding, and insight?
1 Corintians 139-12
9For we know in part and we prophesy in part, 10but when perfection comes, the imperfect disappears. 11When I was a child, I talked like a child, I thought like a child, I reasoned like a child. When I became a man, I put childish ways behind me. 12Now we see but a poor reflection as in a mirror; then we shall see face to face. Now I know in part; then I shall know fully, even as I am fully known.
Looks to me like we have a good chance, if you look at only the passage above. But you have to consider other passages as well.
Isaiah 55:8-10 (New International Version)
8 "For my thoughts are not your thoughts,
neither are your ways my ways,"
declares the LORD.
9 "As the heavens are higher than the earth,
so are my ways higher than your ways
and my thoughts than your thoughts.
This would imply that we can never hope to equal God's knowledge. While I personally believe this to be the case, others might argue that God is speaking to us in our current, lowered estate only, and not speaking to how we will become after the resurrection. I am not able to dispute that with my limited knowledge. I'm not a Bible scholar.
Is this true or is God playing a practical joke?
So far as I am concerned, it is true. God does not play jokes on his creation so far as I know; but my knowledge is currently imperfect, as the passage above states.
Has God put in limits to our learning.
Being separated from God does limit us in this world; but when we are again united with Him, I do not believe there will be a limit placed upon us.
Does god play tricks?
No.
Or are we truly smart and does God need a holiday.
One of the biggest mistakes that atheists make, and I know because I used to be one myself, is this applying human fallacies to a perfect being. Like the constant question of "If God is omnipotent and can do anything, can God make a rock so big that even He can't lift it?" It's a nonsensical question. God is defined as being supernatural, that is "of or relating to an order of existence beyond the visible observable universe". He is beyond the normal space/time continuum that we are able to observe and manipulate. I really doubt he needs a vacation.
I, on the other hand, am made of flesh and most assuredly fallible, so please don't anyone start in on my mistakes. I'm sure I've made plenty. What I've offered is what I believe God's Word has given us that answers your questions.
