We all Have Them

Opportunity Webster say that it's
Fit or convenient time; a time favorable for the purpose; Convenient means.

Opportunities, we all have them sometimes we make the best of them other times we just simply let them go by. Paul tell us in Galatians 6:10-As we have therefore (Whenever we have the) opportunity, let us do good unto all men, especially unto them who are of the household of faith. (family of believers)
Food remnants on dirty dishes, if you deal with them right away, they're soft and easy to remove. Just rinse the plate, and the food falls right off. If you wait, it turns hard so you have to scrape and work, and it's tough to remove it because it's stuck tight. Maybe that's why we call unresolved anger "hard feelings." Anger turns hard quickly, and that gives the devil (enemy) an opportunity to enter a marriage, a parent-child relationship, a friendship, or a church. At the core of every marriage break-up there has probably been an issue that was once a small one, but it was not dealt with immediately. At the core of a broken parent-child relationship, a hurting friendship, or a divided church, there are people who didn't clean up their anger when it first appeared, when it was still small and relatively soft, so it's led to a terrible outcome. The devil got his foot in the door. Today is always your best opportunity to go to that person and do whatever it takes to repair things. Be willing to confront them to apologize and receive or give forgiveness if needed. Talk it through with them and pray together. You say, "Well, that's going to be tough." It won't be as tough as not doing it. You just cannot afford that hard spot in your heart that develops from the anger that you stuff inside. Don't let it grow instead of letting it go. Anger and bitterness never stays the same size; they always grow. Remember the dirty dish. There is nothing to gain in waiting to resolve the problem, because the longer you wait, the harder it gets.
As Principle #3 says “It is easier to keep the heart clean that to clean it after it has been defiled.”
