A Christian strives his entire life to achieve Theosis or deification...i.e. to literally become LIKE God (not God)...this involves many many things, but mostly it involves getting to the point where your free will is in accordance with God's will. It's not that God is taking away your free will, it is that you and God pretty much see eye to eye. If you and I both agree that murdering babies is wrong for example, it's not because I usurped your free will, it's because we both think it's wrong independently.
Once you reach that point, then there is nothing more that you would want more than to be with God. If you and someone are so compatible and think alike and see eye to eye on everything, would you not want to spend a lot of time with that person? Now if that person was God and bestowed great glory upon you, would you not want to spend eternity in that glory.
And as a matter of fact, it is not JUST basking in God's glory. The dead will be raised in a glorious new body. Your reward for being godly on earth is to be YOURSELF glorified. And the dead will be raised in a glorified new body that does need food, water, and drinks. And you will remember your loved ones...and your most beloved will be God.
Not to mention that the alternative is hell fire and brimstone where there is weeping and gnashing of teeth.
