Just saying the word evokes certain feelings and emotions that most of us can identify strongly with. After all, who hasn’t felt the sting of bitterness well up inside of us?
We know that bitterness comes in many forms and from many sources. You may have been done wrong by a spouse or friend. Perhaps you were overlooked for that job promotion. Or maybe you’ve been “church hurt”. And how could you ever forget the diagnosis you received?
All of these can bring about the feelings of bitterness. Some of us may have even felt like God let us down or disappointed us in some way, and we allowed bitterness to cause us to blame God. I’m pretty sure I’m not the only one who has ever screamed at God asking why He allowed ‘this’ to happen.
Personally, I’ve dealt with just about all of these. On many occasions I might add. Just as you have.
Bitterness strikes at all of us, and while it would be easy to simply say it’s all part of our humanity, there is also a spiritual application to bitterness. How bitterness impacts our walk with Christ is the focus of this post.
The writer of the book of Hebrews tells us to “Follow peace with all men, and holiness, without which no man shall see the Lord. Looking diligently lest any man fail of the grace of God; lest any root of bitterness springing up trouble you, and thereby many be defiled”. Hebrews 12:14,15 KJV. emphasis mine
How do we avoid bitterness since we are virtually assured that as long as we remain here on this earth, circumstances are not always going to go our way? How am I supposed to live peacefully with those who have done me wrong? How can I escape bitterness when I’ve been dealt life-altering circumstances?
As we just read, the answer to all of these questions lies in the scripture that encourages us to live peacefully with all men, endeavoring to live a sanctified life, set apart from the world and its many temptations.
More often than not, that means we must have a forgiving heart. More on that later.
Whatever the source, unless we deal with it by giving it to God, it will come back to haunt us in the form of bitterness. That is simply human nature, and none of us are exempt from it. Face it, we are emotional beings. We laugh, hurt, get depressed, feel overwhelmed, and have the capacity to enjoy many things in this life because we are so emotional.
The Lord created us this way, but if we’re not careful, the devil will use our negative emotions as an entrance into our lives. This is why we must be diligent, as the writer says, because Satan is always looking to find an avenue to “steal, kill, and destroy”. 
Allowing bitterness to enter our hearts is opening the door to the adversary, and once opened it can be very difficult to shut that door on him. The danger in all of this is that if even a tiny root of bitterness takes hold in our heart, it begins to weave its way into every fabric of our life.
Picture bitterness as the root of a plant. A plants roots run deep and spread wide. Roots have to do that in order to sustain the plant they are a part of. Those roots feed the plant, and without the proper nourishment the plant will eventually wither and die.
When we allow bitterness to take hold of us, it does everything in its power to burrow itself deeply within our heart. Left unchecked, it will spread into every facet of our life. When that happens, its impact will be seen by all, and it won’t be pretty.
The things that used to bring us joy no longer will. The things we used to look forward to doing we now look at from a very different perspective. That’s what bitterness does to us. It changes our outlook on life, both in the natural and the spiritual. This is why we must constantly be on guard, checking our hearts lest a root of bitterness find its way in.
Let me give you a personal example of how the enemy would like to ensnare us in bitterness.
Recently, our family made the very painful decision to leave the church we had been attending for the past 2.5 years. It isn’t necessary to share the details here, but suffice it to say that these things do happen unfortunately, and they present a myriad of emotions that must be dealt with. In our case, those included hurt, betrayal, and yes even bitterness.
Shortly after we left, I began to have people tell me that they had been told a very different version of what actually happened that caused us to leave. Needless to say, this did not sit well with me because if there is one thing I cannot stand it is when people are not completely honest.
So I was now in a position of either allowing my emotions to gain the upper hand, or let it go and ask God to deal with my heart about it. Which is exactly what He has done. You see, I chose not to allow bitterness to rule my heart.
I hope you caught that. I chose, or I made the conscious decision that bitterness was not going to spring up or take root in my heart. That’s right…bitterness is a choice, and if you and I choose the path of bitterness we are actually giving others power over us.
Why would we do this? This is where having a forgiving heart comes into play. I have learned through many seasons of bitterness and despair that the best course of action is to forgive and move on. Easier said than done? Of course it is, but read on please.
You know what else I have learned? I’ve learned that forgiveness is a product of a heart that is right before God. When we hold grudges against someone, forgiveness cannot come. If we remain angry at someone over a wrong that was done, forgiveness cannot come.
Forgiveness is a product of a heart that is right before God.
I encourage all of us to remember this the next time we’re faced with hurt or disappointment. Choose wisely friends, choose the path of love and forgiveness instead of the path of bitterness.
Be blessed in Jesus name!
