Blaming others is easy, but accountability is hard. To point a finger is always an option, but to address the person in the mirror, requires an internal work.
There will always be reasons outside of who you are, to justify what you said, what you did and how you feel. Yet, these things will not make you a better person.
It may explain what happened, but does not generate growth. There is an unlimited supply of people and situations designed to hurt you, but you are the determiner and you have control.
Be honest about what happened and your culpability in the matter. Sift through each scenario, frame by frame, looking for gaps, flaws and responsibilities in your measures.
Luke 16:10-11
If you are faithful in little things, you will be faithful in large ones. But if you are dishonest in little things, you won’t be honest with greater responsibilities. And if you are untrustworthy about worldly wealth, who will trust you with the true riches of heaven?
