Try this:
1. Buy a cheap Bible. (I bought two of the same so as to clearly illustrate the difference.)
2. Tear out everything that is God using one or a few of His people to address the rest (Pentateuch, prophets, histories, gospels, epistles) as opposed to those "outside," and see how much of the Bible is left. I did. I went page by page and took out everything that is not God addressing "outsiders" and this is what's left:
It's worth noting that, yes most of the Bible in fact gone, but also (1) even a lot of what remains is God simply stating the judgment that is to come for the other nations ("an oracle concerning..." or "judgment on..." and (2) I left Psalms, Provers, Ecclesiastes, and Song of Solomon in because they could be argued to be universal. So yeah, not much "reaching out to the lost" in there, actually.
3. So what's the point?
The vast majority of Scripture is God teaching, reminding, admonishing, and warning His people how to live so the world can see His ways in action; very little has to do with how to be outward focused. SIT WITH THIS for as long as it takes to get that if your "faith" and/or church is built/focuses on outward, quantifiable forms of "productivity" (e.g., evangelism, church growth), something is wrong! (Extra credit: watch this video that delves more deeply into this particular focus.)
4. Keep this Bible as an ever-present reminder of what God actually wants us to focus on (Matthew 22:36-40, Matthew 7:12). Yes we are to "make disciples," but as has been pointed out for a long time now, "as we go," i.e., living as lights, not as recruiters!

What about today? Is there something -- a recurring theme that keeps coming up -- that God may be trying to get through to the many via the few?
God's plan for His church today is the same as it was back in the Old Testament. He put the Israelites in the "crossroads" of their day so that all nations could be exposed to what it's like to truly live and walk with Him, and the church is supposed to be the light in the darkness now. This plan, however, is predicated on His people actually loving Him and each other truly, as He defines love. We obviously need all the help we can get with this; hence, the dominant focus of God's word.
In fact, if we're being totally honest, we in the "American Church" have failed miserably at this...and we will have to answer for it. Or what else do you think Jesus was trying to warn us about in Matthew 7:21-23?
“Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but only the one who does the will of my Father who is in heaven. Many will say to me on that day, ‘Lord, Lord, did we not prophesy in your name and in your name drive out demons and in your name perform many miracles?’ Then I will tell them plainly, ‘I never knew you. Away from me, you evildoers!’"
For my first two or so years as a follower of Jesus, I wholeheartedly believed that this applied to "others" (i.e., those outside my church). Ever since the day I realized that this applies to EVERYONE I have considered this the scariest (as in sobering in a terrifying way) passage in the entire Bible!
Notice that Jesus does not contradict them; He does not say, "No you did not do those things." Instead, Jesus is straight up warning us that we can literally check all of our religion's/church's boxes and still go to Hell!
And in warning us, He (1) literally contrasts God's actual will with our little boxes(!) and (2) boils it all down so simply to not truly knowing us.
It is also worth highlighting that He is not talking to atheists, non-Christians, or folks of other religions, because those folks won't be saying "Lord, Lord!" This is for so-called Christians, and He doesn't say "few" or even "some," He says "many." Let this also sink in.
We read parables like Luke 18:9-14 and, almost subconsciously, see ourselves as the chest-beating sinner. What if we're wrong? Isn't that the point of the parable?? Are we really making every effort (Luke 13:24, 2 Peter 1:5, 2 Peter 1:10, etc.) or do we think we're somehow exempt from such warnings and admonitions?
Yet there is (of course) hope.
But he gives us more grace. That is why Scripture says:
“God opposes the proud
but shows favor to the humble.”
- James 4:6
We must choose humility and dig deep if we are to truly fight for our hearts (Proverbs 4:23), our lampstands (Revelation 2:5), and both our and our hearers' souls (1 Timothy 4:16).
