Biblical Answer

The reason why this had to happen is that God is sovereign over all creation and has a plan for the universe and for humanity. This is evident in the Bible, where it is written that God is the one who "works all things together for good" (Romans 8:28) and that "His ways are higher than our ways, and His thoughts than our thoughts" (Isaiah 55:8-9). This means that God is in control of everything, including the events that unfold in history, and that He has a purpose behind them all.

The question "why did this have to happen?" implies that there must be a causal explanation for the event, and that it must have been necessary for some reason. However, the Bible teaches us that God's ways are not our ways, and that His plans are not our plans (Isaiah 55:8-9). This means that we cannot always understand why God allows certain events to happen, and that we must trust in His sovereignty and wisdom. The Bible also teaches us that God is a God of justice and mercy, and that He will bring about justice and righteousness in the end (Isaiah 51:4-5).

In the context of the Bible, the concept of "why did this have to happen?" is often linked to the question of human suffering and evil. The Bible teaches us that God created a world where humanity has the freedom to choose between good and evil, and that this freedom is a necessary condition for human existence (Genesis 2:16-17). However, this freedom also means that humanity is capable of choosing evil, and that God allows evil to exist in the world in order to bring about greater good in the end. This is a mystery that is difficult to understand, and one that requires faith and trust in God's sovereignty and wisdom.
