They will still bear fruit in old age!!

Psalm 92:12-15

12 The righteous will flourish like a palm tree, they will grow like a cedar of Lebanon;

13 planted in the house of the LORD, they will flourish in the courts of our God.

14 They will still bear fruit in old age, they will stay fresh and green, 15 proclaiming, "The LORD is upright; he is my Rock, and there is no wickedness in him."

How many promises can you count in these verses? Unlike men and women who promise and don't deliver, our Father in heaven keeps his promises.
