My Cup Overflows
If the Lord is your personal Shepherd, then you can say, "My cup overflows with blessings." You can say this because even your trials are turned into blessings when they're in God's hands. He has promised to work them together for good. That means they're blessings in disguise!
You can say this because the Lord is taking care of you, leading you, giving you strength and rest, comforting you, and so on. If the Lord is your Shepherd, your cup runs over with blessing!
Is this your mindset?
