Psalm 94:11 The Lord knoweth the thoughts of man, that they are vanity.

Why does God say the thoughts of man are vain?

Philippians 3:19 Whose end is destruction, whose *God is their belly*, and whose glory is in their shame, *who mind earthly things*.

When our belly is our God, we will spend all our time seeking to satisfy whatever we have an appetite for. For some thats a high paying job, or a nice car, for others its sexual gratification whenever|whenever possible. We all have different appetites as pertaining to things in this world.

But, regardless of what our God|belly wants in this world, its called vainty (Ecc 1). Jesus said it this way:

John 6:27 *Labour not for the meat which perisheth,* but for that meat which endureth unto everlasting life, which the Son of man shall give unto you: for him hath God the Father sealed.

Matthew 6:19 Lay not up for yourselves treasures upon earth, where moth and rust doth corrupt, and where thieves break through and steal:

Jesus said that where our treasure is, there will our heart be also. If the belly|God is where our thoughts are (and consequently our actions) then we are living vain lives that will end with our destruction as noted in Phil 3:19 above.

Colossians 3:2 Set your affection on things above, not on things on the earth.

The way we get heavenly affections is to have the river of God (Holy Spirit) flowing from our belly.
