You’ve heard of the ‘Golden Rule’, it’s taken from the passage in Matthew 7:12;
“Therefore all things whatsoever ye would that men should do to you, do ye even so to them.”
That is a great rule, hence why it’s been called Golden, but there is another rule I like to call the ‘Platinum Rule’.
Let nothing be done through strife or vainglory; but in lowliness of mind let each esteem other better than themselves. [Philippians 2:3]
The word ‘esteem’ is the same word translated as ‘count’ in other passages i.e., Phil 3:7. In that passage, Paul has ‘counted’ all things as loss. Compare that usage to ‘esteem’ and you now have an instruction on how we ought to interact with each other.
Regarding stuff, count it as loss. Regarding people, especially those in the household of faith [Ga 6:10], count them as better than self.
What would it look like if we obeyed the command of our Lord in BOTH of these passages? If you were to ask me how I would describe a Christian, I would begin with these two passages, and perhaps a third;
A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another. [Joh 13:34]
