The vessel must be whole:

But for the vessel to be full,and pure, it must be emptied first...
God's love can not fill you up, if you have not emptied love of self
completely from your vessel.
For if there be any love of self over others first, then God's complete spirit cannot fill you up and run over to others.

If you take a coffee cup and do not clean it out of old coffee,
and later fill it up with water, will it not taste of old coffee?

Such is man's spirit...if there be any love of himself still left inside him, how can God's love complete him...His love will be diluted,
and not full strength...man's love for his fellow man will be the same way, diluted.

Some of man's selfishness will spill over to the next man, and so on...
until the whole of man will have selfishness, instead of love.

Such is the world we see today...man's selfishness has diluted God's love
so that as a whole species, love is remotely displayed.

How can God's love fill up our spirit...? while we dilute it.
How can God's love fill up our lives...? while we dilute it.

Selfishness is like a broken vessel, it can diminish a man's spirit.
It will make the spirit weak, unable to give of itself 100%...
It will make him not want to give of himself completely,
because he will not feel whole enough to give even a little bit of himself,
for fear of losing what he has.

If a man feels not love from his brother,
does it not say that his love is not there for his brother first?
To get you must give first of your own love, for once the void is
created it will be filled up immediatley with more love.

God's love can be construed as a river that flows continuously, and how so?
Even as a river that flows to the sea is replenished by the rains,
so our love will be re-generated by God, if we give it to others first...

Our love for each other is the bonding agent that keeps the vessel of man together...it is like a glue that keeps all our pieces in place,
so that God's love can fill us up with His love,
so our cups can runneth over with it.

So how do we empty our vessels of any selfishness ?
Faith in Him, first of all...
Lose our fear of lack...second.

If we feel lack in anything or anyplace in our lives...we are selfish...
our vessel is broken, love for others is weak, or in short supply from within us...
We can not give fully, because we are not full of love ourselves,
because of the hole that lack has created in our vessel.

When was the last time you felt full of love?
Probably when you gave selflessly, right?
Most likely when you gave to someone else with no expectation
of anything in return...

The love you felt was God's gift to you, to fill your void you made by giving in the first place.

The diluted feelings of love in your vessel were replenished with a fresh supply of love to fill it up again, making your supply even more stronger,
like a broth in a soup bowl...
Some of your selfishness was diluted in turn also by more love from Him to you.

If you give nothing but hate towards others, no love will return to your vessel from others, except by Him, it is always there for you if
you will open up your heart and soul to Him, and accept His love...

Even though our cups may not be full, we should not feel lack, because our cup is not empty at all...we should be grateful that we have anything in our cup at all...even as a crumb to a mouse, we should be grateful for the smallest of things given unto us.
