Declare, exhort, and rebuke with all authority (Titus 2:15)

"Declare these things; exhort and rebuke with all authority. Let no one disregard you." - Titus 2:15

This starts out nice and easy. A command to exhort and rebuke on the Lord's authority. To declare truth and the gospel.

But I don't know what to do with "Let no one disregard you." I know a lot people who have disregarded what I've taught about the Lord time and time again. I can think of one friend right now who has been hassling me about my faith. He knows what I believe and he even knows why I believe it. He just thinks its ridiculous.

How does, "Let no one disregard you," fit with the gospel being "folly to Gentiles" (1 Corinthians 1:23)? That is, if the gospel is foolishness to the non-believer how can we expect them to not disregard us?

If you have ideas please do let me know.

I guess I just want to dwell on what it means to declare, exhort, and rebuke with all authority. To not be ashamed of what we're preaching because it is eternal life or eternal damnation. I want to speak as someone not ashamed, given authority by the Lord to build His church and His kingdom.

Now if I could just figure out how to keep others from disregarding me.

(The only thing I can think is this referring to people disregarding Titus because of who he was rather than the message he was preaching)
