There is an old saying that “bitterness is a hard pill to swallow.” Perhaps a more accurate saying is “bitterness is bad for the digestion.” However, I also like Tom’s Sufis who talk in terms of bitterness entering into the system like a poison and manifesting disease. This disease brought on by bitterness attacks the heart and, once introduced, is difficult to get out of our system. Bitterness is simply taking the poison of another and injecting it into our self.
The cure is not easy, but even bitterness is curable, despite much evidence to the contrary. We rid the bitterness by leaving it no room to grow or exist in our heart. We train ourselves to only accept love and God into our heart. We focus solely on God and his gifts so there is no room for the poison. Bitterness doesn’t give up easily its place. It will test our resolve by the outward presence of those we cannot bear, those we do not like, and those who are intolerant of us. It will present us with difficult situations that tempt us to give it just a little bit of room for it to reside, and as soon as we open the window the poison pours in. Only when we maintain a full and pure heart, full of love, does the poison leave our system. And leave it must. Otherwise we maintain a place in our heart where God is absent.
