After the Israelites passed through the Red Sea and God gave them a tremendous victory they were singing and dancing and praising the Lord. But after three days in the wilderness, they found no water. When they finally came to the waters of Mara they could not drink it because the waters were bitter.  The trials, tragedies &  disappointments of life can cause us to become bitter, sour and negative. Many people are thirsty for a drink of living waters but our waters may be too bitter to drink.  God wants to heal us and set us free from bitterness.  It was at the Waters of Mara that God revealed Himself as YHVH ROPHE (God our Healer).  The primary healing we need is from bitterness. Let us forgive and allow God to heal us.
