The definition of an everlasting God would be a God that has existed throughout time and space, linked to God’s characteristic of being omnipresent, basically meaning that He is present everywhere at all times. This would mean that he is a personal God as he is immanent and is involved with humanity. This back up events like miracles and revelations within the world, as they are caused by God so are evidence of his personal relationship with humans. The definition of a timeless God would mean that God exists outside of time.
This links to the characteristic of God which some believers believe he is; transcendent. This means that God exists outside of time and space so therefore has an impersonal relationship with humanity, meaning He would not be able to influence humanity in the form of miracles or revelations. This view is commonly thought by believers of deism, who believe that an omnipotent God created the world, but then left it to ‘do its own thing and learn from its own mistakes’ and no longer looks over it.
There are more benefits to an everlasting God, mainly because it would explain how miracles occur. However it also means that there can be revelations in the form of praying as a personal God may answer one’s prayers as He is within the universe. Another advantage would be that a personal God can also try to teach us right from wrong and would discipline us like a parental figure.
This is shown in Genesis chapter 1, where God is also shown to have more human-like characteristics and he punishes Adam and Eve much like a parental figure showing his personal relationship with humans. Also the biggest benefit would be that it be proof that Jesus was the Son of God. However an advantage of having a timeless God would be that as God exists outside time and space then he would see all events and therefore he would know everything; past, present and future. This would mean that he would be an omniscient God.
