Then spammers need to spam people who appreciate spam. But they don’t do that, do they?
I'm sure YOU understand the question and it's implications.
First, you're calling God's Word "spam."
Second, you're saying that people who proclaim the true Word of God, people who handle it correctly, people who use it to guide their lives and lead others to the truth - because they know its power... these you call "spammers."
Third, God's Word will not return void. It WILL accomplish it's purpose. You don't seem to be sympathetic to that purpose since you complain about seeing God's Word on a website.
Fourth, maybe you SHOULD read those posts. Maybe you'll be changed. That's a GOOD thing.
