If you have received a massive fortune FROM GOD (everything good is from God) and you are not putting any of it to good use, here and now, then that is clearly wrong. Christians are obliged to spend their talents.
We are not to put our faith in kings, but we are also not to fear the future and scrounge money, rather than being merely prudent. God will provide for us and our children. He said He would and I believe Him, even if they don't.
