Can "we reap what we sow" be a positive, encouragement thought? Obaiah

Obadiah 1:15 (NASBStr)

 “For the day of the Lord draws near on all the nations.

 As you have done, it will be done to you.

Your dealings will return on your own head.

To fully grasp the truths found in Obadiah you have to recall the feud, or struggle between Jacob and Essau.   Jacob would become Israel, the father of the nation.   Essau, who was actually first born and in light to receive all the blessings from Isaac, sold his birthright and blessing to his younger, twin brother, Jacob.   From that day forth and forever Essau failed through sins of commission (doing things agains Jacob/Israel) and sins of omission (failing to do good for Jacob/Israel).   The above verse in Obadiah tells us two great truths that God wants us to remember; negative and positive.   From a negative point of view we have a verse that rehearses the words of Paul in Galatians: Whatever you sow you reap (Galatians 6:7).   If we do wrong you can be assured that the punishment of that wrong will be meted out.   We might think we are the soul person on the earth that God doesn't see and will not exact discipline, but we are mistaken.   It will come.   For the believer the punishment for the wrong of the sin has been delivered to and on Christ.  He paid for the punishment of our sin.  But, we still must handle the circumstances of our sin and the outcome of it.  You can sin for decades in the area of finances.   God can and will forgive you for that.   But, you are in debt the next day.   The lesson above is that God will provide correction for all of our sin.   The positive in the above verse, however, is from Israel's perspective.   If you have someone who is hurting you, has treated you unfairly, does egregious acts against you, or, simply fails to provide you water on your journey, you can be assured that God will deal with them.   "As you have done, it will be done to you," is an assurance for everyone who has has suffered wrong at the hands of a sinful person.   You can rest that God sees it and will deal with it.  It is just better, by God's grace, that we are Israel and not Essau in these life stories.
