To Redeem Time,

is to,

Use your time well;
"Use more diligence in the
improvement of it;
to be diligent and active in
duty and preparation."
(Noah Webster's 1828)

Walk in wisdom
toward them that are without,
redeeming the time
Let your speech be alway with grace,
seasoned with salt,
that ye may know how ye
ought to answer every man.

Collosians 4:5-6
