Athaliah, the Queen, was power hungry. She was so obsessed with it that she set out to kill her own sons and grandsons in an attempt to prevent any of them from taking the kingdom from her.
She was almost successful except that her daughter had a strong desire too: seeing the Lord’s way prevail. She rescued Joash from his own grandmother when he was only a baby and then cared for him while hiding him for 6 years. In the 7th year Athaliah was slain and the child Joash was set up as King.
No matter what scheme the devil may have in place, the One True, all powerful God always prevails. We can take comfort in knowing that we are on the winning side.
