I have learned in my years of raising my sons how to determine the difference between want and need. Many of their requests and yes, demands, were things they simply could not live without. Their lives would be worthless without whatever their particular 'need' was that week.
In trying to be a good parent, I many times made tough choices about wants versus needs. Most of the time, my decisions were not met with gratitude and appreciation. The tough choices were based on finances, safety and appropriateness.
Some of the time we can tell the difference between need and
want but we don't always make the best choices. There are always those things that we absolutely must have. How many of those 'needs' become just one more thing in the closet that we rarely use or even think about?
In the same way, when we go to the Lord with our 'needs',
He doesn't always agree with our assessment of want versus need. He doesn't always immediately provide what we ask for and He doesn't always tell us why.
Psalm 34:9,10 promises that we, His saints, will lack nothing.
We are His saints and His provision is beyond what we could possibly ever want. Matthew 6:33 tells us to seek first the Kingdom of God and all these things will be added unto us.
When we fasten our eyes firmly on the Lord and commit our lives to worship and serve Him, all those 'things' of the world that seemed so important tend to fade in comparison to the Creator of the universe.
