At the Mercy of Others?

"All of us at times find ourselves and our futures seemingly in the hands of other people.  Their decisions or their actions determine whether we get a good grade or a poor one, whether we arepromoted or fired, whether our careers blossom or fold.  I am not overlooking our own responsibility in these situations, but all of us know that even when we have, so to speak, done our best, we are still dependent upon the favor or frown of that  teacher or boss or commanding officer.  We are, from a human point of view, often at the mercy of other people and their decisions or actions...

Can we trust God that He can and will work in the heart of that individual to bring about His plan for us?  Or consider the instance when someone is out to harm us, to ruin our reputation, or jeopardize our career:  Can we trust God to intervene in the heart of that person so that he does not carry out his evil intent?  According to the Bible, the answer in both instances is yes.  We can trust God."
