Proverbs 3:1-2 says, ‘My son, forget not my law; but let thine heart keep my commandments: For length of days, and long life, and peace, shall they add to thee.’
‘Length of days’ and ‘long life’ are two concepts that took a while for me to differentiate.
People are more familiar with the concept of long life, which literally means growing to a full, old age before expiring.
Length of days, on the other hand, expresses a situation whereby the individual who understands its operation is able to milk from 1 day what others attain in a month, or a year!
I know this is not intuitive to the logical individual, but when you realize that (1) time is a property bound to the physical realm, and, (2) God is spirit - He transcends the physical, you will have no choice but to agree that partnership with the Father is the Ultimate productivity hack!
May the Lord give you understanding in these things.
