Anger is a common human emotion and one that is difficult for many people to manage. There are two Greek words used for anger in the New Testament. One is defined as passion, energy and the other is agitated, boiling. Not All Anger Is Sin! Often anger results from a sinful attitude. Other times it has a righteous source. Either way if it is not handled properly it can quickly become sin.
We know that not all anger is sin because YAHUAH gets angry. TEHILLIYM (PSALMS) 7:11 says ELOHIYM judges the righteous, and EL is angry with the wicked every day. When YAHUSHA went into the temple and saw them buying and selling he became angry. And what did YAHUSHA DO??? He made a scourge of small cords and drove them that were taking part in those acts out of the temple. Just about every church building that I have entered into participates in the practice of buying and selling!!! WHAAAAAT! YAHUSHA'S ANGER AT THIS ACT DOESN'T MAKE YOU TREMBLE! IS THERE NO FEAR OF THE CREATOR!
Anger that is prompted by seeing things that go against YAHUAH is righteous in nature. Like seeing the mistreatment of YAHUAH'S people for serving HIM! We also may feel anger when YAHUAH'S Word is maligned or when man attempts to steal HIS glory! But we must remember YAHUAH'S call to humility. PHILIPPIYM (PHILIPPIANS) 2: 3 says Let nothing be done through strife or vain glory; but in lowliness of mind let each esteem others better than themselves. We must also recognize that everything that WE deem as an injustice is not truly worthy of anger. For YAHUAH resists the proud, and gives grace to the humble.
