Filthy lucre is mentioned several times in the New Testament, especially in regards to ministers. Filthy lucre is dirty money, or money obtained through greed. Ministering with a motive for money would qualify as filthy or dishonorably motivated by the advantages and profits belonging to a ministry office. Love for money disqualifies you from the ministry and from the kingdom of heaven.
Not only is the love of money the root of all evil (1 Tim. 6:10), but money in itself is also deceitful. The deceitfulness of riches is one kind of thorn that Jesus said chokes the Word and causes it to be unfruitful in one’s life (Mark 4:19). Money by itself is not bad or evil; it’s a tool and can be a great blessing. We all need it, but it’s deceitful.
Paul warned Timothy about it and told him not to fellowship with anyone who considered gain to be godliness. Sounds like what many preach today, doesn’t it?
“and supposing that financial gain is godliness. Withdraw yourself from such men. But godliness with contentment is great gain. For we brought nothing into this world, and it is certain that we can carry nothing out. If we have food and clothing, we shall be content with these things” (1 Tim 6:5-8).
