This is not true. God has already "enabled" us to be partakers of our inheritance of the saints in light.That is why we inherit the kingdom at the first resurrection with our glorified bodies, spirits and souls intact.
Col 1:12.. Giving thanks unto the Father, which hath made us meet to be partakers of the inheritance of the saints in light:
See the word "meet"? It means "to enable" Do you know what happens when you become "enabled"? It means you have the ability right now to start partaking of your inheritance today!!!
