*Psa 23:1 The LORD [is] my shepherd; I shall not want.*
For every sheep in the fold of the Lord doesn’t lack anything whatsoever. For it takes God himself to supply their needs
*_”The young lions do lack, and suffer hunger; but they that seek the Lord shall not want any good thing” Ps. 34:10._*
This is the promise of the Lord.
The fact that He is your Shepherd and you are a member of His fold automatically makes to _leave the level of wants(lack) to the level of telling God specifically *what you need(desire)* which he would do for you._
