The Lord is my shepherd, I shall not be in want. Psalm 23:1
There's almost nothing more tender than the picture of a shepherd lovingly caring for his sheep.
Jeremiah 23:3-4 demonstrates a good shepherd's heart - to gather, protect and feed His sheep, so that they shall "be fruitful and increase." Jesus, our good shepherd, does all this through shepherds (pastors and teachers) He appoints over His people. Their role in representing Him is not be beat (shame) or fleece (financially exploit) the sheep, but to feed them such that they "shall fear no more, nor be dismayed, nor shall they be lacking."
Now, what is this "food" that brings the sheep to the place of no fear, no discouragement and no lack? It is "the Lord our Righteousness." The more you feed on teaching that reveals Jesus and the gift of His righteousness through faith in His finished work, the more you'll experience freedom from fear, depression and lack. So pursue ministries that carry Jesus' heart for His sheep, that boldly proclaim the Lord our Righteousness and that reveal His abundance of grace - and experience His fruitfulness and increase!
