If you were in paradise what would you be doing? What would you be feeling?
In this world you may not be able to do what you want to do in paradise, but insha Allah you can at least feel that way.
"Indeed in this world is a paradise and who ever does not enter the paradise of this world will not enter the paradise of the hereafter. "
This is referring to the sweetness of Iman. If you do not taste it in this world you will not reap its fruits in the hereafter. What are some signs of sweetness of Iman that you want to strive for:
1- To love Allah and His messenger beyond all else.
2- To love and want to be loved for Allah's sake alone.
3- To hate to return disbelief just like you would hate to be thrown into the fire.
