Sometimes we Christians say words that non-Christians don’t understand, but sometimes we don’t understand them either. They’ve just become buzz words that we throw around and feel good about.
Go do some digging about these words, even if you think you know what they mean. Look for their context in the Bible as well as their literal dictionary meanings. Dig into things like divine providence, repentance, salvation, savior, worshipping in spirit and in truth, God’s will and what it is to follow it, being a disciple, loving your neighbor, even the word Christian itself.
Could I just dig into these and answer them for you? Yes, but then you won’t go do it and get anything out of it yourself. Let your curiosity spur you into some digging!
