Practical Atheism

Romans 1:21 -For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened.

Militant Atheism

Much has been made over the last few years regarding the emergence of militant atheism’s evangelistic crusade to rid the world of ignorance. Specifically, these crusaders want to enlighten the minds of the masses who still believe God exists. For these spokesmen for atheism, belief in God is intellectually unsustainable and should by all means be abandoned. Not only that, these atheistic evangelists believe a person’s commitment to belief in God is actually harmful to children as well as to civilization as a whole.

Thankfully, their charges have been sufficiently answered at every turn by faithful Christian apologists. The atheists are getting all the press, but their arguments are unable to stand up to the Light of Truth.

A More Dangerous Breed of Atheism

Yet there is a more prevalent form of atheism that lurks in our land. Indeed, it can even be found in the church. It is what Cornelius Van Til called, “practical atheism.” A practical atheist is a person who professes to believe in God, and yet the God whose existence is professed does not seem to make any meaningful difference in that person’s daily life. His beliefs, values, morals, and actions are not prioritized by his supposed belief in God’s existence. Put another way: If this person was to wake up one day and decide he no longer believed in the existence of God, his life would change very little. This is practical atheism.

In Romans 1:21, Paul describes the person who has suppressed the truth he knows about God. Paul says that, in truth, all people know God exists. In fact, they even know things about his power and majesty. Yet, in order to maintain a certain way of living, they alter their belief system to accommodate their lifestyle. Like the hard atheist who formally declares there is no God, practical atheists deny God by the way in which they live their lives. Paul teaches us that “although they knew God, they neither glorified him as God nor gave thanks to him…”

God at the Center

We glorify God when we seek to live purposefully and intentionally for him each day. We glorify God when we live to please, honor, obey, love, represent, bear witness to, and imitate him. That’s what a God-glorifying, God-informed life looks like. It’s also a life that is grateful to God for his goodness. This is more than tossing out a “thank you” every now and then at the beginning of a meal. Instead, it’s more of an all-encompassing attitude of gratitude. It becomes pervasive in one’s personality. This attitude glorifies God because it exalts God as the One who is worthy of such affection and appreciation.

How are you doing with this? Are you seeking to glorify God and be thankful to him in all things? Of course, none of us is perfect at this. We can all get fairly self-absorbed and self-centered in the goings on of our lives. We all, from time to time, become too preoccupied with lesser interests.

Yet the One who should be our greatest interest has told us we are to have no other gods before him. We are called to seek him first and foremost. We are instructed and encouraged to be holy because God is holy. His existence, in other words, should play a profound role in the lives of those who profess to believe in and follow him. He should be our ultimate influence and his influence should saturate every sphere of our lives, for his glory and our good.

Walking Points

  • What are some of the ways you have observed people “suppressing the truth they know about God.” Why do you think they do so?
  • Have you found yourself doing the same – living throughout the day, making decisions, and behaving with little or no reference to God?
  • What are some ways you can more intentionally live for God each day?
  • Talk to a trusted Christian friend about this devotion, brainstorm together, and then hold one another accountable.


Heavenly Father, the whole of creation testifies to your existence. It’s truly amazing what we have to go through to deny that you are there and are not silent. And yet, you are the God who is not to be merely believed in. Instead, you are the Triune, personal God who calls us into a relationship with yourself. You first loved us, not because we were so good, but because you are. You are our loving Father who is worthy of our love and devotion. Indeed, to know and love you is to seek to become increasingly like you and obey your commands. In my own strength I will fall short of this. Therefore, loving Father, I humbly ask you to please fill me with your Holy Spirit and spur me on to greater and greater love for you. And, I pray, this love for you will influence every sphere of my life so that, one day, my whole life will be a shining testimony of your glory. In Christ I pray. Amen.
