But you remain the same,
and your years will never end.
Since we are part of creation, us human beings are confined to time and space. Time is something we can not alter. We can not make it go faster or slower, ie we have no control or dominion over it. Nor can we escape from its influence. We are all subject to its passage and even though sometimes we would like to reverse what has already happened, we can not change things. Wise King Solomon said it this way: “What is crooked cannot be straightened; what is lacking cannot be counted.”  This time limitation is what makes it so hard for us to understand the concept of eternity. God is eternal because he is not subject to the passage of time. He exists outside the domain and the advance of time.
Given that God exists outside and above that domain, he can see perfectly what has already happened, all that is happening now and what will happen in the future. I imagine that God observes the creation in much the same way that we see a chronological representation of certain historical events. We can see what happened before the event and the event’s influence on following events. We can also see other events that occurred in parallel with the event in question and finally we see the precedents that led to the event under study. In front of our eyes would be the past, the present (when the event occurred) and the future, ie things that would happen later. Of course, this is just an illustration and in no way it is intended to be declared as a fact that this is the way God sees things. Nor can we know how it feels to not be under the constraints of the laws of time.
In any case, God is eternal. He has no beginning and no end. He has always existed and always will. He has all power and all the majesty over creation. Someday, I hope soon, the heavens shall pass away and we who have placed our trust in God we will see a new heaven and a new earth, for the first heaven and the first earth have ceased to exist, just as the sea. All that remains is God and his promises, which never fail. Let us be amazed when we consider this particular attribute of God and let us rest in his power and eternity. Hopefully the time will come when we will be in his presence for ever and ever. To God alone be the glory! Ecclesiastes 1:15
