It’s okay to be angry, it’s okay to be mad, it’s okay to just sometimes even feel a little upset. It doesn’t make you any less of a christian, it doesn’t make you any less spiritual or loved by God. The key to walking out your spiritual practice is found in Ephesians 4:26 where Paul says that in your anger; sin not. Do not make brash decisions out of anger. It is great wisdom for you to simply take a deep breath and cool down before making any decisions especially anything that will be detrimental to the situation or even cause lasting harm. One of the fruits of the spirit is self-control. This means being able to control one’s self regardless of the situation or circumstance. As people of faith we do not live by our feelings or emotions for we know that they can sometimes lie and deceive us. Some mornings we wake up on the wrong side of the bed and just aren’t feeling it. As believers, we operate off of faith and what we know to be true even if we can’t see it or at times don’t even feel like it. We operate off of what we know. The Bible also talks about the fruits of the flesh and the opposite of self-control is fits of rage. The fruits of the spirit follow those who live a life of consistently walking with Jesus and fellowshipping with the father in the spirit and in truth. These are natural qualities that will accompany the believer and should be prevalent in all of our lives. Walking in the spirit is an action and it’s something that we do not just something we are. The Bible speaks about carnal Christians and those who live according to the flesh and do the opposite of what Christ taught. This is why we must examine our hearts and emotions to see whether we are in the faith; for our lives will truly confess what we believe. This is why the scripture says that without works your faith is dead but yea by our works we do establish our faith. The fruit that you produce at the end of the day you will show what you truly believe by your actions. Again this is a really deep principle and a universal thought throughout the scriptures. The Bible also talks about not letting the sun go down on your anger and there are many reasons for this. One of the reasons is that it’s we are open vessels to receive wisdom and knowledge from heaven but if you have anything that clogs up the mind (in the spirit) it is much harder to receive downloads. You must always deal with the last thing that God tells you and nothing can go overlooked; this is the key of walking in intimacy and with God and people. The anointing will remain upon your life if you are a person who can righteously deal with their own inner conflict as you go through life in the threshing process. You must remember to keep your hands clean and your hearts pure for the river of life to continuously flow through you without hindrance. I believe a lot of this is taken care of by simply obeying the scripture, in your anger sin not.
