Our time is a precious commodity of unknown quantity.

"Redeeming the time, because the days are evil." - Ephesians 5:16 KJV

"Walk in wisdom toward them that are without, redeeming the time." - Colossians 4:5 KJV

What does Strong’s lexicon say “redeeming” means?

2) to buy up, to buy up for one's self, for one's use

a) to make wise and sacred use of every opportunity for doing good, so that zeal and well doing are as it were the purchase money by which we make the time our own

If we use every moment of our day for God’s will, a witness to everyone that the Lord brings across our path, and doing whatever the Lord would have us to do, our time is redeemed giving it eternal value that cannot be taken away.
