While there are a number of countries that have practiced atheism as the official position of the state, there are only three countries that currently practice state atheism: the People’s Republic of China, North Korea, and the Socialist Republic of Vietnam. Yet even within these officially atheistic countries, religions flourish. Wherever humans exist, the longing for God is ongoing.

This reality reflects the words of King Solomon near the end of his life. He recognized that God “has put eternity in [men’s] hearts”—that is, a longing to connect with man’s Creator. Solomon also observed that “no one can find out the work that God does from beginning to end” by simply recognizing His existence. General revelation—for example, nature (Romans 1:19-20)—can show us God exists, but it takes special revelation—through the written Word and living Word, Jesus Christ (John 1:14)—to show us how to fill the God-shaped vacuum in our heart.

If you long to know God, begin by putting your faith in Christ as your Lord and Savior.

There is a God-shaped vacuum in the heart of every man, which cannot be filled by any created thing, only by God. 
Blaise Pascal
