Do not assume the title is anything different from what it says. You will reap what you sow and that goes for anyone and everything. Think about the things you see happen or the things you've seen people do and decisions he or she has made. That voice inside sometimes tells you its going to be hell to pay when xyz comes back around. Recalling a statement from the book "As a Man Thinketh" by James Allen, the author wrote Good thoughts bare good fruits, and Bad thoughts bare bad fruits. Or, every man is where he is in life because of his thoughts and actions. Thus, bad choices will have consequences that one must ultimately endure. With that in mind the Bible says, "Do not be deceived: God cannot be mocked. A man reaps what he sows. The one who sows to please his sinful nature, from that nature will reap destruction; the one who sows to please the Spirit, from the Spirit will reap eternal life."
Following several self evaluation reviews and hours of reflection, I wanted to do my best to attempt to right any wrongs within my life. This included apologizing for anything I had done to hurt someone, or at least addressing any issues I thought caused another to view my choices or actions with any form of resentment. Obviously, people are going to judge or feel a certain way about you regardless of the success or failures, but I felt it was important for me to at least clear my conscience. Freeing one's mind of any guilt will allow you to move forward in your personal growth. As far as what someone else chooses to do, or feel, that my friend is out of your control. Don't worry about it.
People often misunderstand or are oblivious to the consequences of their actions. People will treat others badly or even judge, and look down on others as if they will never make a mistake or come across their own challenges. We have to remind ourselves that we too, do not always get it right. How you choose to treat others and the bridges burned, can isolate you to the point where there is no one left for you and your thoughts, or friendship. No one left that wants to hear your complaints, or bare your burdens. No one to lift you up in your time of need or pull you out of those dark clouds. Reaping what you sow refers to the fact that you are likely to receive the same problems that you create for other people.
