Its Jesus of course. The parable is basically talking to the whorder, one who stores up money and possessions that he really doesnt need in order to satisfy his lusts of the flesh and desires. This person bought everything under the sun, from houses to cars, to "you name it I got". After all is said and done and money is spent on his wildest desires, he still desires more, but has nothing else to buy. So instead of giving away his money or possessions ( I mean not just giving it away, but wisely sowing "seed" into the less fortunate, building homes for the homeless, providing for the helpless, etc) he puts his millions into an account and decides he will die with his money rather than live without it and help others. Jesus says in Matt 6:19 "Do not store up for yourselves treasure on earth(where it can be disposed of, paraphrase) but store up treasures in heaven(1st love for God, humble heart, giving nature, love for others, daily relationship with Jesus, etc.), for where your heart is there is your treasure. His heart was bent on greed, not the love of God. You cannot serve both Money and God, as He created wealth.
The word Jesus focused on was covetousness. God had blessed the man abundantly, but he became selfish and greedy! He didn't reconized that it all comes from God! And he was not rich in Spiritual things! He never used any of it for the Kingdom! And gave none back to God! 2Cor.8:9... Jesus became poor that we would become rich In all things! He created and owned the vast universe Eph.3:9..Col.1:15-18.. He laid aside His riches and everything else to redeem us. Through that we became joint- hairs of God with Christ of all that God owns. Rom. 8:17..Haggai.2:8.. It is His will that He blesses and prospers us in all things! 3John2..as long as we recognize that it all comes through Him and if we use it for His Glory and for the Kingdom! Mal. 3:8-12..It doesnt matter how much a man has weather it be one house or two, If he is a man of God and is giving into the kingdom and knows his source is God then he is worth of his hire. Luk.10:2-8...Genaveve
