Here's basically what the person said (I've condensed it greatly):
"Heaven will be so great, no crying, no tears. You'll get to see your loved ones. You'll walk on streets of gold. You want that don't you? Won't you give your life to Christ right now?"
All that is true enough, but there's a problem. It wasn't the real Gospel. It wasn't even what Jesus taught. It was a religious version of consumerism, i.e., "I don't want to suffer and Jesus is what I have to get to get no more suffering."
Now you need to know that I have zero concerns about the person making these comments, about their own trust in God, their own motives. They sincerely believed they were saying good words about God. But there was, ironically, no God in their Gospel. If I was listening correctly (and it's entirely possible that I wasn't), Heaven is a really nice place where apparently I won't be bothered by God.
John Piper, in his book, God is the Gospel, asks a question we all need to ask (emphasis added):
The critical question for our generation—and for every generation—is this: If you could have heaven, with no sickness, and with all the friends you ever had on earth, and all the food you ever liked, and all the leisure activities you ever enjoyed, and all the natural beauties you ever saw, all the physical pleasures you ever tasted, and no human conflict or any natural disasters, could you be satisfied with heaven, if Christ were not there?
