Proverbs 14:24 The crown of the wise is their riches: but the foolishness of fools is folly.
25 A true witness delivereth souls: but a deceitful witness speaketh lies.
These two verses seem to things in common in that the fool is always up to no good and brings nothing but shame for their action. In the fools folly they are constantly lying to lead people astray and into destruction. They are full of nothing but Satan himself.
On the other hand we see that the wise are true witness of the Gospel of Christ. When we do what God says in spreading the the gospel we are blessed beyond measure in material things as well as spiritual things. We are rich because we are children of God. By being the witness we can be we are also leading souls to the saving grace of Jesus Christ. Sometimes I think we too much emphasis on material things of this world when our greatest treasure awaits us when we leave this world and gain our heavenly home.
