Luke, chapters 10 & 11

“[…] Give as gifts of mercy the things that are from within, and look! everything about you will be clean.”
~Luke 11:41

What are the things “from within?”
Jesus has been asked to dine with the Pharisees and has reprimanded them for outwardly appearing to be spiritual while hiding greediness and wickedness within. (Luke 11:39)
“The one who made the outside made also the inside, did he not?”
Jesus explains God’s justice and love, which we are capable of imitating, should be our main focus.
Then he further denounces their religious hypocrisy. (Luke 11:40,42,44)
So when Jesus says to give gifts from within, he appears to be alluding to sharing generously from a pure heart, with selfless motives.
The attitude with which we give stems, of course, from the way we choose to think. (Jer. 4:14)
At the end of the day, God is looking at whether or not our love is sincere. (1 Pet. 4:8,9)

Deuteronomy, chapters 23-27

“You must not bring the price paid to a female prostitute or the price paid to a male prostitute into the house of Jehovah your God to fulfill a vow, for both of them are something detestable to Jehovah your God.”

~Deuteronomy 23:18

This is essentially a law against money laundering.

The principle that God doesn’t want dirty money calls to mind the story of Judas and the 30 silver coins he got from betraying Christ (Matt. 27:5).

After committing a grave sin, a person might feel compelled to right a wrong through financial methods.

But serious wrongdoing can only be erased before God if there is a turning of the heart (Eze. 18:31).

More important than the amount a person or entity donates to a charity are the spirit and means that were used to acquire that money.

Was it whole-hearted honest labor? Was it through the sale of something dear and valuable?

If we are living morally unclean lives, we cannot just buy a seat in the house of God’s true worship. Salvation would be a mere illusion (Eze. 7:19).

Religions hold a great deal of the blame, as they habitually accept considerable donations from organized crime members, a sin for which they will be held accountable (Rev. 18:4,5,8,24).
