Matthew 13:20-21

20Other seeds fell on soil with rocks in it. This is like some people who hear God's message. These people are happy to believe it for a time.

21But they are like plants that have not grown down well into the soil. So they only believe for a short time. They may have problems. Or other people may do bad things to them, because they obey God's message. When that happens, these people soon stop believing.
