I found an interesting article where a Christian woman explains how she used to share her testimony with non-Christians. But that wasn’t working. So she decided to try something different.
I’ll never forget the first time I shared my personal testimony with a non-Christian.
When the opportunity arose and I shared my story with an unbelieving friend, she replied, “That’s so cool. I’m so happy you found something that works for you.”
“It’s not about what works for me,” I said, trying to hide my discouragement. “It’s about what’s true for everyone.”
“That doesn’t make sense,” she responded. “That’s your experience, not mine. I had a similar revelation when I realized I could leave the church, and I’ve become a better person for my decision. Just as you were freed from your heaviest burdens by finding God, I was freed from mine by leaving God behind.”
I was devastated but I chalked it up to my friend’s hardheartedness. I decided to shake the dust off my feet and look forward to the next opportunity.
But time after time of sharing my testimony resulted in similar responses. People expressed enthusiasm that I was happy, that Christianity worked for me, and that I had “found my niche.” Yet no one considered my experience as anything more than just that—my own personal experience.
[…]I had been taught that sharing what God had done in my life was the ideal way to witness to non-Christians. A personal testimony was interesting yet non-confrontational, compelling but inoffensive. And yet, despite having shared my testimony with dozens of unbelievers, not a single person felt challenged to consider the truth claims of Christianity.
She noticed that her approach wasn’t actually in the Bible. There was a different approach being demonstrated by Jesus, and later by his disciples.
When Jesus called his first disciples, he taught truth and provided evidence (miracles) to support his claims, then he asked people to follow him (Luke 5:1–11). In fact, this was his method whenever he went into new regions (see Luke 4:14–44; John 4:7–26). People decided to follow Jesus not on blind faith or a subjective feeling, but based on the evidence they had seen and heard.[i]
Jesus also used evidence to assuage the doubts of even those who had been with him a long time. John the Baptist was Jesus’ cousin, who leapt in the womb during Mary’s visit (Luke 1:39–45), baptized Jesus in the Jordan River, heard God’s voice from heaven, and saw the Holy Spirit descend on Jesus in bodily form like a dove (Luke 3:21–22). Yet when John experienced unexpected suffering, he began to doubt.
Jesus didn’t respond as many do today, by insisting that John “just believe” or “have faith” or “prayer harder.” Rather, he responded with more evidence, saying, “Go and tell John what you hear and see: the blind receive their sight and the lame walk, lepers are cleansed and the deaf hear, and the dead are raised up, and the poor have good news preached to them. And blessed is the one who is not offended by me.” (Matt. 11:2–6).
[…]At Pentecost, the apostle Peter offered signs and wonders, fulfilled prophecy, and relayed eyewitness testimony to persuade people from all over the Roman Empire that the most reasonable explanation for what they were seeing was not morning drunkenness, but a risen Messiah (Acts 2:1–41).
On his missionary journeys, the apostle Paul reasoned with the Jews from the Scriptures, explaining and proving that Jesus was the Messiah who needed to suffer and rise from the dead (Acts 17:1–3, 17). And he reasoned with the Gentiles from outside the Scriptures, making a case with their own accepted beliefs to convince them (Acts 17:17–34).
In fact, in describing his mission, Paul told the Philippians, “I am put here for the defense of the gospel” (1:7, 16). This word translated defense is the same word from which we get our English word “apologetics,” meaning to make reasoned arguments or to provide evidence as justification. Using this same word, Peter commanded believers to “always [be] prepared to make a defense to anyone who asks you for a reason for the hope that is in you”(1 Pet. 3:15).
So, she decided to dump the testimony approach, and try the Biblical approach. But she had to change it a little bit, since she couldn’t perform miracles herself:
We are not eyewitnesses to Jesus’s life and resurrection, but we have the accounts of those who were. We don’t typically see miracles, but we have millennia of biblical scholarship and archaeology that provide reasons to believe the accounts are trustworthy. We don’t often hear God speaking audibly or see him parting seas, but we have significant scientific evidence that shows the universe had a beginning, and millennia of observation to confirm the scientific principle that everything that begins to exist has a cause.
I think a lot of Christians never move on from approach she described that wasn’t getting results. And there’s a reason for that – studying evidence is hard work. But I can tell you from my experience as a software engineer, there is no better way to convince other people to adopt your view than to show them working code that produces results. If they have a prototype, they will adopt your design. Similarly with Christianity. If you have evidence, then you will be persuasive.
When talking about spiritual things with non-Christians, always remember the joke about the two men walking in the woods who meet a bear. One man starts to put on his running shoes. The other man says “what are you doing? you can’t outrun a bear!” And the first man says “I don’t have to. I only have to outrun you”. It’s the same with apologetics. You don’t have to be William Lane Craig to talk about your faith to non-Christians. You just have to know more than your non-Christian opponent knows about evidence.
The way things are going these days with the public schools and the mainstream news media, this is actually pretty easy to do. One or two introductory books on the origin of the universe, the fine-tuning for intelligent life, the origin of biological information, the origin of body plans, the historical reliability of the New Testament, the minimal facts case for the resurrection, etc. will do the job. You might need another one on philosophical challenges like evil, suffering, divine hiddenness, etc. But we’re talking no more than 5 books, and you’ll be effective in the vast majority of your conversations. If you can only get one book, I like Sean McDowell and Jonathan Morrow’s “Is God Just a Human Invention?” best.
