In Exodus 15, the Bible tells the story of the Hebrew people who were traveling from Egypt to the promised land of Canaan. For three days the people had traveled in the wilderness without finding any water. Finally, they arrived at an oasis where water was, but the much needed water was bitter, and not safe for drinking.
Although God had miraculously led them across the Red Sea just days before, the people forgot to call on God and began to complain about their situation.
When Moses prayed to God for help, God showed him a certain tree which could be thrown into the water and the water would become drinkable.
This story reminds us that we will all face many bitter and disappointing situations in life. Instead of becoming complainers like the Hebrew people, we need to turn to God for help in times of need.
The solution to our problems may be close by, just like the tree that Moses used, but we may not see it. God might use something already within our reach if we will just call on him for help.
