The Lord is our Shepherd, and in Him, 'we shall not want' (lit. "be lacking") but so often we get distracted. We become consumed with life's obligations and we stray further from our Shepherd. This doesn't happen overnight, it happens in moments throughout days that turn into months, that turn into those 'seasons'. We find that we have not yearned for the Lord as we should have, nor relied on Him as we ought and need to. Our condition is a stray sheep in need of return.
Back in Florida, a college pastor of ours preached through the entirety of the Bible - one book at a time each Sunday morning until he was finished - Malachi was one of my favorites. I remember he labeled Malachi as a book about spiritual apathy. A particular verse that has somehow always struck me is Malachi 3:7 which says, "From the days of your fathers you have turned aside from my statutes and have no kept them. Return to me, and I will return to you, says the LORD of hosts. But you say, 'How shall we return?'" The book of Malachi specifically discusses the Israelites neglect of the Law and how the foreign influences were becoming a dominating part of their culture - from intermarrying to divorce. The condition of the nation was just not good, even the priests were neglecting their duties in favor of foreign practices - which is one reason why the prophet addressed the priests harshly in chapter 1. This verse is telling us that God is different than the his ow laxidasical chosen people - and He is different from us. We continually stray, but God has mercy on us for if we return to Him, He will indeed return to us. Malachi 3:6 says, "For, I the LORD, do not change..." And surely He does not.
