Consider this short passage from Psalms 34,
"O fear The LORD, ye His saints: for there is not want to them that fear Him. The young lions do lack, and suffer hunger: but they that seek The LORD shall not want any good thing." [Psa 34:9-10]
Those who fear The LORD will not suffer need, they will not be wanting. This doesn’t mean that those who fear The LORD will have lots of wealth or physical things on this earth. No, but the opposite, because those who truly fear The LORD aren’t going to be desiring worldly things. The Fear of The LORD will bring contentment with whatever God decides to give us. We will look at our circumstances and be satisfied, knowing that The LORD has provided it.
Notice here too that fearing God and seeking Him are connected. A true fear of God results in seeking Him. And if we are seeking The LORD, then He will provide us with our needs. As Jesus says in the Gospels,
"Therefore you should not be anxious, saying, what shall we eat? Or, what shall we drink? or, wherewithal shall we be clothed? (For after all these things do the Gentiles seek: ) for your Heavenly Father knoweth that ye have need of all these things. But seek ye first the kingdom of God, and His righteousness; and all these things shall be added unto you." [Mt 6:31-33]
And so when we truly fear God, we will seek Him. And when we are seeking Him above earthly things, our needs will be provided. Therefore, if we are continually fearing God and seeking Him, we can be content with whatever God gives us because we know that He is providing as He promised.
