All in Godly
Anger, in and of itself it isn’t necessarily a sin, but unbridled it can lead us to the wide gate of sin, as certainly as the road to righteousness is hard, and the bridge to life is narrow. The way from anger to murder, or hating your brother is an easy walk... so we must always ask ourselves “do you do well to be angry?” Then, If our anger is justified... ask “Do I have it under control?”
Whether you are a believer or not, rest assured that this world will come to an end, and for those of faith... you will meet God face to face. So how do we prepare ourselves for this meeting? Should we be perfect in our recitation of scripture, or study diligently the nuances of faith? No, any scholar can do such; we should be doing those things we read, and are told by God... we should live holy lives, and conduct ourselves in a godly manner.
