Matthew 7:6

New King James Version (NKJV)

6 “Do not give what is holy to the dogs; nor cast your pearls before swine, lest they trample them under their feet, and turn and tear you in pieces.

• Pigs/Swine don’t appreciate the beauty/value of the pearl if its found under its feet 
• Dogs don’t care if the meat/food is from Altar or from garbage

Pigs/Swine : people who don’t value your pearl

Dogs : people who don’t value you/God’s children

Answer

• Our life, time, energy, opportunities and abilities are God’s pearls. They’re His!
• whatever we make/create are holy, because we are separated unto God. We are God’s children.
• Don’t cast it among people who don’t value it or among people who don’t care about it
• Make sure you discern through the wisdom of Christ, on to whom you are casting it to.

Note: Even if you don’t cast on to the right people, again you are wasting those pearls.
