One does not have to wait for death to enter into the kingdom of God. If one becomes a pure chanter of the holy names of God, he can actually enter into the kingdom of God even within his present body.  This is described as follows by Srila Prabhupada in his purport to Srimad Bhagavatam 2nd Canto, Chapter 2, Text 30:

"The first stage is the offensive chanting of the holy name, and the second is the reflective stage of chanting the holy name. The third stage is the offenseless chanting of the holy name of the Lord. In the second stage only, the stage of reflection, between the offensive and offenseless stages, one automatically attains the stage of emancipation. And in the offenseless stage, one actually enters into the kingdom of God, although physically he may apparently be within the material world. "

So we don't have to wait for death to enter into the kingdom of God. We simply have to master the art of chanting the holy names of God without any offense.
