Three Secret Seeds by Joyce Reason
From the Junior Gateway Books series - a series of simple, easy-to-read stories in large print with a Christian message. Peter, Caroline and Jennifer are staying at the seaside. Peter is thoughtless and a tease, Caroline has a bad temper and Jennifer is always afraid. Jennifer prays hard that she will become brave. When she rescues her baby brother from the sea, her mother tells her that Jesus has planted a seed of courage in her heart. If she waters it with prayers it will grow big and strong. This story tells how two other seeds are planted and what happens next.
