Jesus said to the religious leaders of His time ...
Jn. 8:44 ... Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
Devil does not live in the truth ... there is no truth in devil.
He speaks lies.
Devil does send thoughts to our minds.
When income reduces, it is not unusual for devil to send thoughts as to what is going to happen to us in future ... and if we stop and consider, those fearful thoughts of future are opposite to that which God says about the subject and what the inspired word of God, the Holy Scriptures, say to us about the subject.
Not enough money in future? Will have to sell house and move to less expensive location? And your house won't sell because of the economy?
Bible: God says ...
Hebrews 13:5 ... 5 Let your conversation be without covetousness; and be content with such things as ye have: for HE (God) hath said, I will never leave thee, nor forsake thee. 6 So that we may boldly say, The Lord is my helper, and I will not fear what man shall do unto me.
Phil. 4:19 ... But my God shall supply all your need according to HIS riches in glory by Christ Jesus.

If we need to make a change, God will show us. If we need to reduce expenditures, God will show us. Pray, ask God if you need to do anything, any adjustments ... be persuaded by God not by devils.
If you've taken on too much, too many "good works", ask God to show you.
I've had many times during the past 30 years that income has reduced. I've often asked God if I need to cut back and if so "where".
So far, God has never shown me that I need to reduce expenditures and all my needs have been provided abundantly ... even more than before, though my income now is greatly reduced from 10 years ago.
Ephesians 3:20 ... Now unto HIM that is able to do exceeding abundantly above all that we ask or think, according to the power that worketh in us,

Sometimes thoughts will come to us concerning that which is going to happen to us "tomorrow" ...
When tomorrow concerns us, we should pray, committing those fears of tomorrow and dreads of tomorrow to God.
Doing as Paul said to do:
Phil. 4:6-7... Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.
And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus.

Lay the entire situation out before God in prayer ... Allow God to establish your thoughts on the matter at hand... Wait on God until HE shows you... Give it time ... Don't rush into anything ...
