my portion and my cup

LORD, you have assigned me LORD, you have assigned me my portion and my cup; you have made my lot secure. The boundary lines have fallen for me in pleasant places; surely I have a delightful inheritance. Psalm 16:5-6 (NIV) ; you have made my lot secure. The boundary lines have fallen for me in pleasant places; surely I have a delightful inheritance. Psalm 16:5-6 (NIV)

This has been a very assuring verse for me when years back i had been going through unstability and delay .Again while searching for a house in a new place, the Lord guided me thro' this verse.

How much security this promise offers to those who believe , to know that our Lord is in contrl of our lives.
