Luke 8:13-14

Those on the rocky soil are the people who, when they hear, receive and welcome the word with joy; but these have no firmly grounded root. They believe for a while, and in time of trial and temptation they fall away [from Me and abandon their faith]. The seed which fell among the thorns, these are the ones who have heard, but as they go on their way they are suffocated with the anxieties and riches and pleasures of this life, and they bring no fruit to maturity.
