Your question is wonderful , but basically it depends on you, if you are a child of parents ,how do you know they are your parents. By there presence also, they care for your needs. Our Heavenly Father also cares from a grand scale. He continues to care for things we have no control of, the sun ,moon and stars. Our planet is perfect for our habitat as humans and animals, we do not fly out in space, and from protective force fields we are protected from many destructive meteors, we have just enough oxygen to fill our lungs, and we have gifts ,the earth to care for ,and animals, true that many do not appreciate these wonderful things, because everything that is good they contaminate, and destroy the natural use. It is like a beautiful aquarium with exotic fish, you care for them ,but you must not be careless ,the tempt must be just right and the water environment with enough salt water or what they thrive in, even to the point that they are not alone, they have companions. Our Heavenly Father who created all things can be found in the original Hebrew and Greek writings ,his name is Jehovah! His name was given to Abraham, Moses ,and Jesus made his Fathers name known also. Reference Bible Ex 3:15 Then God said once more to Moses: “This is what you are to say to the sons of Israel, ‘Jehovah the God of YOUR forefathers, the God of Abraham, the God of Isaac and the God of Jacob, has sent me to YOU.’ This is my name to time indefinite, and this is the memorial of me to generation after generation.
Even Jesus was concern about his Fathers name in the prayer he taught us ,this is a key to the right God.
,Reference Bible Mt 6:9 “YOU must pray, then, this way: “‘Our Father in the heavens, let your name be sanctified.
How can you if you do not know his personal name?
That is the key to to the beginning of a personal relationship,
Your parents gave you a name too!
What your name represents is up to you.
What Jehovah name means, he causes to become, meaning he is the God of the living not of the dead.
Reference Bible Mt 22:32 ‘I am the God of Abraham and the God of Isaac and the God of Jacob’? He is the God, not of the dead, but of the living.”
So fitting that many that died will return. Because they are in his memory that they keep living.
What does this all mean is just like your parent you have a relationship with ,So can you. For a book carries the thought and intention of the Author so does the bible. Continue to read it. And for help as and aid wwwjworg will help you .
