Psalm 23 is such a classic Bible verse that seems simple, but it is very complex when applied to life. I grew up hearing it in Spanish from my grandma Clarita. For many years now, God has been showing me through various life trials and opportunities - that He is my Shepherd and with Him, I lack nothing. And this supply and demand to be the Good Shepherd isn't limited to me. It's to all God's children. That is glorious wonder of our God!
