OP... Jesus acknowledged that this world is under the control of Satan when dealing with him in the wilderness for forty days.
There is a war going on at all levels, from the physical, environmental, molecular, cellular, mental, financial, political, religious, spiritual, and emotional. Bottom line is that God is the good guy from whom all good things flow. The devil is the evil one from whom all wickedness reigns.
God's solution to this war, is first gathering all His people together in truth and faith. The second step is to cleanse them from the sin the entraps them. He starts with the mind, heart, and soul of the person. By free choice, they have opened up their heart to Him, asking Him to come into their lives and lead them.
This is the step of faith, for it takes that leap to even consider talking to "God", let alone believe He exists. There is evidence still left on this earth, from the plants that still grow, to the kindness and unselfish love still in the heart of some people. He calls those His remnant. Reason being there are not too many around.
Your family has been war torn in a battle that you can only see the devastation physically. Long before this came about, the Lord was involved. He is a gracious gentleman and only goes where He is invited. He is not one to give His gifts to those who think He is like Santa Claus and is only there to gratify them in their present state. Every move the Lord makes is calculated towards saving us.
You need to pray for a face to face meeting with God. He promised that He will come and talk with you one on one in Rev 3:20. Understand you are asking to speak with the Holy One of Israel. The Bible is full of instructions on how to meet God and what to expect. The Bible is also full of individuals (prophets) who have met God and what they experienced. He is that same God as the one who walked the earth as Jesus.
When you meet with Him, ask Him to explain all the devestation around you. He will show you every effort He made, the battle the raged, the part you played in all this and why the outcome. He has it all written down in a book which He calls the Book of Life.
Get real with Him and He will get real with you.
