Science reports recent Hubble discoveries that show galaxies millions of light years from earth. If the light we see TODAY is from these galaxies, then that means the light left the surface of the galaxies far beyond the existence of the earth due to the distance it travels. We know that light travels 186,000 miles a second and the earth was created in 6 days. But if the statements are true, then either light must travel faster than the known calculations OR the galaxies are closer to us than what is reported.

So how do we witness to people who argue these things?


First, there are many variables to the statements made by science.  For one thing, we don’t know for certain that the speed of light is constant. Textbooks reference Einstein’s theory of special relativity that sets the speed of light at 186,000 miles per second (300 million meters per second) and say that the speed of light is constant, but over the last couple centuries, there have been studies that suggest the speed of light is decreasing.  Additionally, photons (light particles) have a drag coefficient and are subject to friction so we don’t know that light travels at the same speed in deep space.  For more information, visit and 

So let’s answer the question:

How do we witness to those who argue what science reports? 

The answer is: in the same way we witness to anyone. Don’t spend time arguing scientific facts. That’s debating science.  It’s not witnessing about Jesus.  Address the statements, but then turn the conversation to one of spiritual importance. 

  • Ask if the person has ever considered where they will go when they die?  
  • Tell them that Jesus opened the way to eternal life with God.  
  • Ask if they think they are good enough to go to Heaven.  

If they answer, yes, and say they are good enough to go to Heaven, then ask why?  They’ll probably tell you that they are a pretty good person.  Tell them that “good” isn’t good enough to get into Heaven.  One has to be perfect…but no one can be.  So God sent His Son.

Tell Them About Jesus

Jesus, who is God, entered into our world and took on flesh.  He lived the perfect life,  He took our sins upon Himself, He died to pay for our sins, then was buried and three days later rose from the grave, conquering death and opening the way to Heaven.  

Share the gospel of saving grace with those who desire to argue science reports. Tell them they need to turn to Jesus and trust in Him for the forgiveness of their sins.  But always do it with kindness.  

In your conversation, don’t deny their interest in science. Briefly address the science issues, the best you can.  But then move on.  Don’t let a debate about science direct the conversation or cloud the importance of the gospel message.  Be bold, be kind, and be wise. Share the love of Jesus and tell of His desire to give salvation to all who repent and trust in Him.

Be Ready Always...

to give a reason for the Hope that you have (1 Peter 3:15).  When you can’t share the gospel with your words, share it by leaving tracts that tell people about God's grace.

When leaving a tract, always be diligent to pray about the short gospel message. Pray that it be found by someone who is in need of Jesus’ saving grace, and pray that the person will have a tender heart and open ears to receive the gift Jesus desires to give them.  

By the power of the Holy Spirit, even a small tract can help in turning a broken sinner from darkness to light.
