Mark 4:16-17

16 Some of the seeds fell on soil with rocks in it. This is also like some people who hear God's message. These people are happy to believe it for a time. 17 But 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 because they obey God's message, other people may do bad things to them. When that happens, these people soon stop believing.
