My counter to this is we've tried to make the world better. However, the message is being rejected. It's clear the message is being rejected.
They have made it clear they do not want to hear the message or follow the message.
Your counter is 100% correct and exactly how I see it as well.
There has to be a point where the message is just not registering with anybody new and the declining returns amount to nothing.
You would be very hard pressed to find somebody alive today that has a phone who has never heard of Jesus.
