"Therefore do not worry, saying, 'What shall we eat?' or 'What shall we drink?' or 'What shall we wear?' For after all these things the Gentiles seek. For your heavenly Father knows that you need all these things. But seek first the kingdom of God and His righteousness, and all these things shall be added to you." (Mat 6:31-33)
The original sense of nakedness was from that deep insecurity of autonomy that sprung from man's first alienation from God due to sin-- spiritual death. Seeking God marks man's refusal to stay alienated by turning towards His Maker in whom alone is Covering and true Security and no reason to be ashamed anymore.
