The inscription on my new tee shirt, a birthday gift from my daughter, read in big bold letters the Latin phrase, “PURGAMENTUM INIT, EXIT PURGAMENTUM,” an old Latin phrase I came across many years ago. On the shirt, beneath that inscription, it read in smaller red letters, “GARBAGE IN, GARBAGE OUT.” My children heard me state those same words many times as I attempted to influence what they watched on television or at the movies, the kinds of the music they listened to, and the books they read.

‘Garbage in, garbage out’ was a phrase popularized during the early days of computers, meaning that if faulty programming were put into them, faulty results would come out. This applies to us as humans, too.

The human mind is a wonderful and extremely complex computer. In fact, during the earliest days of space exploration, a dedicated group of African American women received the nickname of “computers,” since they were using their minds to compute very complicated mathematical formulas that would make launching men into space possible. Their story is told through the theatrical film, “Hidden Figures.”

Receiving daily input. However, as with any of today’s electronic computers, what comes out of the human mind is no better than the value or validity of what is programmed into it. We begin receiving data while still in our mother’s womb, and we continue receiving input – information of all kinds – throughout our lives. This vast collection of data shapes our development of the ways we think and respond to the world around us, ultimately our personal worldviews. One’s worldview determines values, and these values in turn influence one’s behavior. In spite of this reality, many of us go through life without ever considering the validity or truth of those things that have shaped our thinking.

Until I began to read what God, the Creator of all things, had to say in the Bible, I too had never taken time to examine what was influencing my thinking. Whether as a fighter pilot during the Vietnam War or a commercial airline pilot, I never paused to wonder, ‘Why do I think the way I do? What factors have served to influence and form my values, opinions, and the things I hold dear?’

Conformed to this world? However, after becoming a follower of Jesus Christ, I began to read the Word of God and discover statements like this from the apostle Paul, who wrote in Romans 12:2, “Do not conform any longer to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God’s will is – His good, pleasing and perfect will.” Was the information I was taking in from the media in all its forms conforming me into the “pattern of this world”?

With the myriads of written publications, television, films, radio, and the Internet, we live in an era of information overload. We are constantly being bombarded with all kinds of data, some of it good, some of it not good at all. After reading Romans 12:2 and other passages from the Scriptures, I realized if I am to maintain clear thinking, my challenge is to sift through all of this information and determine which is valid and based on truth, and which is based solely on the shifting sands of culture and godless values.

Finding the way to truth. To effectively make these assessments, I concluded that it is necessary for me – and I believe for all of us – to ensure that we are programming our minds, our ‘computers,’ with what we know to be true. As Jesus said, recorded in John 14:6, “I am the way and the truth and the life.” Knowing Him and seeking to follow His teachings in the Bible is the best way to avoid the trap of “purgamentum init, exit purgamentum” – garbage in, garbage out.

Reflection/Discussion Questions

  1. When you hear the phrase, “Garbage in, garbage out,” what comes to your mind?
  2. With all the information that’s available to you each day, whether through the print or broadcast media, the Internet or other sources, how do you decide the way you process that data and how it influences you?
  3. What do you think it means to be “transformed by the renewing of your mind”? How does this differ from being “conformed to the pattern of this world”?
  4. Jesus Christ claimed that He is “the way, the truth and the life.” How can or should this declaration affect how we approach each workday – the job assignments we handle, the people we meet and interact with, our overall goals and objectives, the way we assess truth?

NOTE: If you have a Bible and would like to read more, consider the following passages:
2 Corinthians 10:2-5; Philippians 4:8; Galatians 5:22-23; Colossians 3:2-10; 1 Peter 1:13-14

Challenge for This Week

This week, find someone you can talk with candidly – a trusted friend or advisor, mentor, or accountability group – and together evaluate how you are doing in terms of “purgamentum init, exit purgamentum”: garbage in, garbage out.

Consider what steps you are taking to ensure that your natural computer – your mind – is being filled with the right kinds of programming, the right data to enable you to be and to become the person that God wants you to be.
