Lack means to be without or to have less than a desirable quantity of something: to lack courage, or sufficient money. Need often suggests even more urgency than does want, stressing necessity. Require occurs most frequently in serious or formal contexts: “Your presence at the hearing is required.” When the bible uses the phrase, “nothing lacking,” what comes to mind? Because those who revere the Lord, lack nothing.
Psalm 34:9 — Fear the LORD, you his holy people, for those who fear him lack nothing.
James 1:5 — If any of you lacks wisdom, let him ask of God, who gives to all liberally and without reproach, and it will be given to him.
1 Thessalonians 4:12 — That ye may walk honestly toward them that are without, and that ye may have lack of nothing.
Luke 22:35 — And he said to them, “When I sent you out with no moneybag or knapsack or sandals, did you lack anything?” They said, “Nothing.”
