2nd Kings 12:11 And they gave the money, being told, into the hands of them that did the work, that had the oversight of the house of the Lord: and they laid it out to the carpenters and builders, that wrought upon the house of the Lord, 12 And to masons, and hewers of stone, and to buy timber and hewed stone to repair the breaches of the house of the Lord, and for all that was laid out for the house to repair it.
So, let’s recap what took place here. Ahab, and the infamous Jezebel were the progenitors of Ahaziah, who followed in the footsteps of Ahab, and Ahaziah has a son, namely Josiah, who chooses to track an entirely different course. It's worthy of note that the training Josiah got from an early age at the hands of the priest Jehoiada, had a profound effect upon his mind, and according to the Scriptures, those early instructions played a vital role in overriding whatsoever genetic, and inherited tendencies to evil Joash’s progenitors bequeathed.
Thus, even though this is the exception rather than the rule, yet, it is possible, by the grace of God for a person to buck that downward trend, set in motion by one’s parents and grandparents. If it were not a possibility, then the grace of God would have limits on its ability to save to the gutter-most. [2] The other statement from our first passage that needs to be addressed is that of “Keeping mercy for thousands of generations that love me and keep my commandments”
The generations of the righteous are promised grace and mercy, but this isn’t exclusively theirs, as we’ve seen in several previous passages. If the offspring of righteous do evil, in many cases they would reap the natural results just like the wicked because The Lord does not generally interfere with the laws of sowing and reaping.
Galatians 6:7 Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap. 8 For he that soweth to his flesh shall of the flesh reap corruption; but he that soweth to the Spirit shall of the Spirit reap life everlasting.
May God add His blessing to the study of His word. “Good night” and God bless!
