God, being Creator, understands our being. He knows our structure, our frame. He knows our weaknesses. Where we are weak and where we are strong. The Bible allows a widow to be remarried or to have another husband. This is because there will be no problem in the resurrection of the dead according to Matthew 22:23-30.
The passage tells us of a woman who has been a wife of seven men. They are asking a question in the resurrection which of the men seven of them will be acknowledged as the husband of the woman. The Lord Jesus Christ said, You err because you do not know the scriptures nor the power of God. For in the resurrection, they neither marry nor are given in marriage but they are like as the angels of God in heaven.
Therefore, there is no problem even in the resurrection when your father will be resurrected and your mother and the second husband. There will be no fight there. There will be no jealousy there. Why did you marry another man?Because there will be no more marriage in the world to come in eternal life. We will all like the angels and our children of God because we are children of the resurrection.
The Lord Jesus Christ teaches us in the resurrection there will be no problem.
