IS THERE ANY EVIDENCE THAT GOD EXISTS?
Science is the systematic knowledge of the physical or material world, gained through observation and experimentation. Science is constantly evolving, and theories are constantly changing, for example - the world was thought to be flat, but was later discovered to be round. Science is based on the physical and material world using the five senses. However God and His kingdom does not fall into the physical and material realm. Therefore to understand God and His kingdom we need to acquire this understanding through the power of thought.
Advanced science requires intensive research and study. For example, in order for a scientist to understand that the atoms and molecules exist, they have to invest a lot of time and energy. We as common people accept what the scientists have to say in regards to theories as we do not have the time and capacity to learn and understand this. In the same way, intensive time and energy is needed to develop the power of thought through which one can see into God's kingdom and receive His messages. However, contrary to science where we have come to accept changing / modifying theories (for example earth was thought to have been the centre of the universe, until it was proved otherwise) the ideas presented by persons in the knowhow of God's kingdom have not changed, but have added to the existing knowledge base (for example, first we only knew that God exists, but now we know of God and His archangels and angels).
As mentioned elsewhere on this site every person can learn to communicate with the good Spirit World and this site can assist anyone who sincerely wants to.
