A favorite argument of those trying to push the boundaries of Christian ethics is an argument from silence. It usually goes something like this: "Jesus never talked about [insert issue], so that means He doesn't care."
However, arguments from silence are a type of logical fallacy. The lack of evidence for something does not mean the gaps in our knowledge should be filled with assumptions. Furthermore, every parent who has heard their child say, "You didn't see me do it," understands that those who depend most heavily on a lack of proof might not be prioritizing the truth.
When it comes to the Christian life, arguments from silence are more than just sloppy thinking. They might also be evidence of a heart that is more interested in getting its own way than trying to live God's way.
Fundamental to the gospel is the idea of submission. Paul expressed this attitude when he wrote, "I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me" (Gal 2:20, ESV).
When we justify our morally questionable decisions with an argument from silence, we put the cart before the horse. Our goal should not be to do whatever we want until someone says, "No," but to affirmatively look for ways to honor God with our lives.
Instead of asking, "Is it okay if I do this?" we should be asking, "Does God want me to do this?"
The first instinct of a life surrendered to God is to find out what He wants, not to see if we can justify doing what we want. As Christians, everything we do should be viewed through the lens of honoring God. As Paul said, "[W]hatever you do, in word or deed, do everything in the name of the Lord Jesus, giving thanks to God the Father through him" (Col. 3:17).
The instinct to see what we can get away with is evidence that we don't always want God to be in charge. We want Him to supervise and provide help when needed, but mostly we want Him to help us have fun. In his book The Problem of Pain, C.S. Lewis described that view of God in this way:
We want, in fact, not so much a father in heaven as a grandfather in heaven--a senile benevolence who, as they say, "liked to see young people enjoying themselves" and whose plan for the universe was simply that it might be truly said at the end of each day, "a good time was had by all."
The God of the Bible demands daily submission for His glory and our pleasure because He loves us and understands that our sinful desires promise joy and satisfaction but deliver neither.
Even Jesus, who is fully God and an equal member of the Trinity, was primarily focused on what God the Father wanted Him to do. As Jesus said, "Truly, truly, I say to you, the Son can do nothing of his own accord, but only what he sees the Father doing. For whatever the Father does, that the Son does likewise" (John 5:19).
It is folly to build our moral view of the world around what Jesus did not talk explicitly about. After all, Jesus didn't say anything specifically about sexual assault or flying planes into skyscrapers, yet we can still know what God thinks about them. As Christians, our desire should be to think biblically about everything. Even though the Bible doesn't provide explicit instructions on every issue or question we may encounter in life, the answers are not difficult to find if we actually want to find them.
When considering what Jesus said and thinks, our attitude makes all the difference. Any time we find ourselves saying, "Jesus didn't say you can't..." is a good time to take inventory of our motives and make sure that we are really wanting what God wants and not merely trying to justify doing what we want.
