Summary: Marah is bitterness and Marah situation only happen when someone find his/her self in wilderness that was what happen to the children of Israel in the wilderness.
23And when they came to Marah, they could not drink of the waters of Marah, for they were bitter: therefore the name of it was called Marah."
According to the Bible Marah was in the wilderness. And we all know that wilderness is not a pleasant place to go or to experience. I want you to understand that Marah was not the original name of that place; it was called "Marah" because the water was bitter.
What happen you come across Marah; people begin to call you name that is not yours. In Luke 18:35 (quickview)  "And it came to pass, that as he was come nigh unto Jericho, a certain blind man sat by the way side begging:" This man was blind for years and at the same time begging, but what I want to bring out here is that, the blind man has a name but nobody cares about that the only thing people can remember of him is that "he his a blind man" this is an example of one that find his/her in Marah. The same thing is what the happen to woman with the issue of Blood for 12years the Bible called her “the woman with the issue of blood” but she has a name that was given to her.
Marah is a bitter situation, it is a time when people forget your real and refer to called you by the name of the situation your are facing. Many people who have being sick for months/years you find out that people are begin to call you by that name of the sickness. It is not that they have forgotten your name, but it gives them pressure when they called you by name of the sickness because it remains them of your weakness. But some are ignorance of what they saying and damages they have done. Would you blame them? It is because the devil uses those around to torment your life.
Pray this prayer for yourself: You the Spirit of Marah operating in my life die in the name of Jesus"
Looking the out the children of Israel; they must have cried and prayed to God for water in next village and getting to Marah they were happy that there is water, but by the time try to drink of it, it was bitter. This mean almost half of them must have rushed into the river to drink the water what a disappointing situation. Before they decided not to drink of it that means it was very bitter because one could have expected that after 3 days dry hunger fasting they would manage whatever they see. Pray this prayer for yourself "Every bitter water flowing in life, dry up in the name of Jesus
This experience is not far from many people today, the more they try to get breakthrough the more they disappointed. Pray this prayer with determination: every situation in life that will make me loose focus on God die the name of Jesus.
