What does the Bible say about the eternality of God?

The eternality of God means that He always is and has never had a time when He wasn't present. Romans 1:20 states that the invisible things of God are clearly seen, understood by the things He has made, showcasing His eternal power and divinity. This concept is essential as it reaffirms that all things exist because of Him and His purpose, and time itself is a creation of God. The significance of this attribute is that it not only underlines God's omnipresence but also assures us that He is constant and unchanging in His nature and promises.
