God is the self-existent One, having no need of being created, since He has existed forever and is the cause of all things, including the dimension of time, to which He is not subject. Likewise, God is not subject to the physical creation, but is spiritual in nature, residing in the spiritual dimensions of heaven.
God’s power over the physical creation is absolute, such that He can manipulate matter, energy, space, and time at will. For this reason, God is said to be all powerful, able to accomplish any possible task He wills to do.
Along with being all powerful, God is also all knowing—having knowledge of all things that are possible to be known, including the entire history of the universe, past, present, and future. Because God is all powerful (omnipotent) and all knowing (omniscient), He is also able to be present at all places at all times (omnipresent).
"But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth."
