When we find ourselves feeling down or distressed, and we begin to withdraw, one thing is for sure, God knows exactly how we are feeling and where to find us, as was the case with Hagar when she ran away from Sarah into the desert. (Genesis 16)
David reminds us in the Shepherd's Psalm that "even though I walk through the darkest valley, I will fear no evil, for you are with me; your rod and your staff, they comfort me." (Psalms 23:4) David had a clear view that he was not forgotten nor forsaken.
Time and time again we see in the Scriptures that either God himself, or somebody He sends, comes to encourage His followers.
Elijah running away from Jezebel sat down under a broom bush and prayed that he may die. Twice an angel of the Lord came to lift him up before the Lord himself came to Elijah and encouraged and strengthened him for what lay ahead. (1 Kings 19)
Irrespective of where you find yourself at this point in time, God is able to use you to encourage someone who needs to be encouraged. He, through Holy Spirit, can give you the gift of encouragement. He took Elijah from inside the dark cave and used him to anoint Elisha as his successor.
