Everything in existence is governed by divine law. The prophet Alma said:
"The scriptures are laid before thee, yea, and all things denote there is a God; yea, even the earth, and all things that are upon the face of it, yea, and its motion, yea, and also all the planets which move in their regular form do witness that there is a Supreme Creator." - Alma 30:44
The prophet Jacob talked about how he knew about the mission of Jesus Christ:
"And I said unto him: Deniest thou the Christ who shall come? And he said: If there should be a Christ, I would not deny him; but I know that there is no Christ, neither has been, nor ever will be.
And I said unto him: Believest thou the scriptures? And he said, Yea.
And I said unto him: Then ye do not understand them; for they truly testify of Christ. Behold, I say unto you that none of the prophets have written, nor prophesied, save they have spoken concerning this Christ.
And this is not all—it has been made manifest unto me, for I have heard and seen; and it also has been made manifest unto me by the power of the Holy Ghost; wherefore, I know if there should be no atonement made all mankind must be lost." Jacob 7:10 - 12
We are hear to be tested and tried and to see if we will follow and seek out all the divine laws of God. To those that seek out more, more is given, to those that seek out less, less is given. It is a knowledge factor based on one's willingness to seek out God, learn of his will and study and follow His word.
As I said earlier, all things that denote there is a God is staring us right in the face. However, if someone does not wish to believe in God, they don't have to believe. They can come-up with theories of men and excuses as to why there is not a supreme creator but that is all they will ever be.
If someone does not want to seek-out God, they are not forced to. God respects agency. He will not force someone to do and see something they don't want to. A "Miracle" is God's power working through someone dependent on their diligence and willingness to seek out God and God is able to use His power through that individual that is connected to divine law.
Based on that, from what I know and what I have experienced through my studying and praying and seeking to know Him and His will, I know that God lives. I can feel Him when I earnestly pray in faith. I have had prayers answered. I have seen miracles and I have had the chance and ability for God to work through me to bless other individuals.
Based on that, there is no question that God exists. There is nothing that someone can do that can take away from what I know about God. As the prophet Jacob said, God speaks to us through the power of the Holy Ghost. We have to be in tune to feel that power. When you feel it, it can be an overcoming feeling that extends beyond anything that the natural eye can see.
To be in tune, it cannot just be a mere curiosity and just be going through the motions. One must have the actual burning desire to know of the existence of God and have the desire to follow Him and His will and repent of any sins that one may know that they have committed, meaning forsaking that act and confessing it to God and possibly making restitution to anyone that was offended or wronged.
That is what being in tune means, aligning one's will with God's will. God cannot dwell in unholy places based on someone knowingly rebelling against His will. Jesus Christ is importance to this formula as well because what he did for mankind bridged the gap between us and the Father.
No one is perfect, we all fall short so he has become an intercessory between us and the father. Because of that, those that don't know God's laws and ignorantly disobey eternal laws are still not severed from God through Jesus Christ. Those that do know his laws and don't obey His will are severed for willful rebellion.
As a result, Jesus Christ has standards that one has to follow to get back in tune with the Father. As mentioned, they must repent and forsake sins and have a desire to learn and know and follow God's will. This is the plan of redemption. It is freely available to all mankind.
When you start obeying God's laws you will start to fill the Holy Ghost in your life which can guide and direct you to where you need to go and what you need to do. The Holy Ghost is also a cleanser and sanctifier. It will lift a person up to new heights that were not possible with merely their own strength, they can overcome weaknesses, fear, doubt ect. through this process.
This process allows someone to return back to the presence of the Father where we were with Him from the start as a resurrected being thanks to the redemption of Jesus Christ. We lived with Him as spirits prior to this life and we are here to learn and grow with mortal bodies and see if we would do all that we were commanded to do on this earth.
We are all searching to be content. We are all yearning for something more in this life. What we are searching knowingly or not is for the feeling we felt when we lived back in the presence of our Father. People may have found supplements, but true Happiness and Joy are only experienced through grasping onto eternal truths and allowing for Jesus Christ to fill in the gaps with our own ignorance of all truth.
So, in my mind, the question of whether or not God exists makes no sense. The real question should be, what have I done in this life to seek out God and follow His will and draw toward Him? Have I followed His commandments to the best of my ability? Or do I have remorse of conscious still of things past that still have not been cleansed through Jesus Christ? Have I had a sincere conversation with God before or lately? Have I studied any of the words of prophets that have been connected to God lately as an intent to learn who He is? Have I asked Him for forgiveness of actions I knowingly made against Him? Have I ever felt the redeeming love of my Savior Jesus Christ through this process? Have I ever sung the song of redeeming love? Are my hands clean? Are my motives pure?
There will come a time when we will all stand before the Savior Jesus Christ and give an account to Him of our time spent on earth. So are you ready for that moment or are you stuck on debating whether or not He even exists?
If you really want to know if God exists, then study His word, and ask Him. He will let you know. It may take time to get aligned and in tune to get an answer, but once you get in tune, you will get an answer. I promise that. Then you will now that God exists and you can move forward with that concept and following His will.
So what should happen, instead of debating the matter, everyone should just take the matter to God and ask Him and come back with your results. If you have questions or concerns you can ask them. If you aren't getting an answer, you can ask why and and what you have done to receive an answer on here. Then from there, we will have a forum of people who now know of the existence of God and can tell how they learned of the existence of God and how they felt. Or if someone has already learned of the existence of God, they can share their experience on how they came to learn of the existence of God.
It is all a personal thing. No one will know what I felt and what I feel when I pray and when I study and when I act and help and serve others, it must be experienced personally. The purpose of angels and prophets and scriptures and miracles is to help lead people to the water and to the invisible eternal laws of God but in the end, it is their choice on whether or not they want or choose to drink.
