When the Lord God Almighty decreed that the sons shall inherit the kingdom, by no means did he intend to exclude daughters. Sons are a euphemism for all of humanity. When Jesus returns to establish his kingdom, he will assign responsibilities based on the condition of the heart. Individuals will be assigned to countries based on their preference, and they will be assigned tasks based on their competency. They will know their level of competence so that there will be no discord in regard to levels of responsibility. They will know the condition of their heart merely by looking at it in the ether, and determining whether it is gold or white, grey or black. Black hearts will mean that the person is righteous but did not realize that their heart needed to be cleansed.
God will not cleanse their hearts for them in order to promote them. He will expect them to have done the work prior to his return. He also will expect them to have asked for advice from the indwelling Holy Spirit of God on the methodology for cleansing the heart. If they do so, and their heart is cleansed, they will have discovered the source of every sin condition, and its solution. They also will have discovered the source of every methodology for ensuring that we have an appropriate "Welcome Back" celebration for our Lord and Savior, Jesus Of Nazareth. The Lord our God, Jesus Of Nazareth, reigns in all the earth. Amen.
