Did God Have a Beginning?
▪ The Bible answers that God did not have a beginning. God has always existed. As difficult as the concept of God’s eternity is to grasp, we cannot dismiss the idea simply because we cannot fully comprehend it.
How reasonable is it that we should expect to understand all of God’s ways? The apostle Paul declared: “O the depth of God’s riches and wisdom and knowledge! How unsearchable his judgments are and past tracing out his ways are!” (Romans 11:33) Our minds cannot fully grasp the depth of God’s wisdom and knowledge any more than an infant can understand all the ways of a parent. These inspired words of Paul, although primarily about the uniqueness of God’s wisdom and mercy, suggest that there are aspects of Jehovah God and his workings that are too deep for our minds to fathom. The concept of God’s being without a beginning is apparently one of them. Yet, we can have absolute trust in what the Bible teaches about God. Jesus Christ said regarding the sacred writings: “Your word is truth.”—John 17:17.
Moses said in prayer to Jehovah: “You have always been, and you will always be.” (Psalm 90:2, The Holy Bible, New Century Version) Here Moses describes God’s existence as stretching in two directions. One is toward the future. Jehovah is “the One that lives forever and ever.” (Revelation 4:10) Thus, God’s existence stretches forward into the eternal future. The other is toward the past. In other words, God was neither created nor did he come into existence. Rather, God’s existence stretches back into the infinite past.
