Sometimes we allow our circumstances to cause us to become discouraged and discontent. We see an example of this in Ruth when during the time of Israel's famine Elimelech did not "dwell in the land" where God wanted him. Instead he chose to go to Moab out of God's will. He was not content. He did not "feed on God's faithfulness," but fed his own desires and longings taking matters into his own hands.
Denying oneself and not giving into fears is never easy. God never promised us easy, but He does promise us His best if we choose His ways. Feeding on His faithfulness can enable us to choose His paths.
An example by contrast is Abraham. He did feed on God's faithfulness and followed Him. Genesis 25:8 says, "then Abraham breathed his last and died in a good old age, an old man and full of years [satisfied with life], and was gathered to his people." Let's make the choices today that when we look back we will be full and satisfied with life. Let's finish well!
