2 Peter 3:3-4 AMP

“First of all, know [without any doubt] that mockers will come in the last days with their mocking, following after their own human desires and saying, “Where is the promise of His coming…”

We are not short of doubters in this world. We have doubters that are without Christ and we have doubters in churches all across the globe. But we cannot focus on them, we only have time to focus on our own path and making ready as many as we can before His coming.
