HOW GOD OPERATES

2 AND YOU SHALL REMEMBER THAT THE LORD YOUR GOD LED you all THE WAY THESE FORTY YEARS IN THE WILDERNESS, to HUMBLE YOU AND TEST YOU, TO KNOW WHAT WAS IN YOUR HEART, WHETHER YOU WOULD KEEP HIS COMMANDMENTS OR NOT.
3 SO HE HUMBLED YOU, ALLOWED YOU TO HUNGER, AND FED YOU WITH MANNA WHICH YOU DID NOT KNOW NOR DID YOUR FATHERS KNOW, THAT HE MIGHT MAKE YOU KNOW THAT MAN SHALL NOT LIVE BY BREAD ALONE; BUT MAN LIVES BY EVERY WORD THAT PROCEEDS FROM THE MOUTH OF THE LORD.
4 Your garments did not wear out on you, nor did your foot swell these forty years.
5 You should know in your heart that as a man chastens his son, so the Lord your God chastens you.
6 “THEREFORE YOU SHALL KEEP THE COMMANDMENTS OF THE LORD YOUR GOD, TO WALK IN HIS WAYS AND TO FEAR HIM."
Deuteronomy 8:2-6 (NKJV)

There are a number of things which whoever wants to walk with God should understand. Some of these things are not always emphasized by preachers or teachers of God's Word. They usually do not tell people about how God humbles and tests whoever wants to walk with Him (Deuteronomy 8:2).

A woman
A woman, believer in Christ, came several years ago, asking to know about some changes she was experiencing. She had been laid off from her work, she was a single parent or a baby mama, and it was her siblings who were supporting in a number of ways in terms of meeting some basic needs. She was later established, started a business, but the usual supports that she usually got were stopped. She started wandering, asking, Could it be that those who were supporting her at the time of distress had forgotten her? I said No, it was a change of season for her. Manna had to stop because she has entered the promised land, that is, the new business she started. Those free things would no longer come, she would need to work and make her money before she could get whatever she wants. In the promised land, you would need to till the land, plant, do the weeding of your farm and then harvest. It would not be usual way of waking up in the morning to go out into the field and gather manna, you have to work or labour for whatever would be gotten.

The Israelites were humbled and God allowed them to hunger (Deuteronomy 8:3). He fed them with manna which they did not know, and led them in the wilderness for forty years (Deuteronomy 8:3-5).
Why did God do that to them?:
a. To humble them and test them, to know what was in their heart, whether they would keep His commandments or not (Deuteronomy 8:2). God does not bless arbitrarily or aimlessly, He would want to know your heart and know whether you are fit or appropriate, qualified or fitted, for His blessing and lifting or not.
b. Another reason why the Israelites were humbled and tested with hunger is that they might be made known; man shall not live by bread alone, but lives by every word that proceeds from the mouth of the Lord (Deuteronomy 8:3). In other words, whoever is of God should not live by bread or food alone, but the word that proceeds from God's mouth. All your aspiration should not be about what you would eat, the house you would build, the cars you would buy, and other material things you would acquire; but your aspiration should be about knowing God's mind or will about whatever you are doing or wanted to do in life. You should always be beholding His face to know whatever He is saying per time. The primary responsibility of a believer is to always palpably looking up to God to know His mind or will, either you are in the secular work or ministry work. When this is missing in a believer's life, such has lost fellowship or communion with God.

The Israelites clothes or garments were not worn out, and their foot did not swell in the forty years of their journey in the wilderness (Deuteronomy 8:4). They were chastened when they erred (Deuteronomy 8:5). All these were done that they might understand God, and He wanted them to be obedient to Him: "THEREFORE YOU SHALL KEEP THE COMMANDMENTS OF THE LORD YOUR GOD, TO WALK IN HIS WAYS AND TO FEAR HIM (Deuteronomy 8:6).

Most of the time, believers who professed to be of God do not understand Him, even as they read the Bible, they could still not understand or know Who He truly is (Hebrews 5:12-14).
God does not just bless. God has principles and patterns of doing things. The woman I shared her story thought she would just be building her business and other things she used to receive would just be flowing in, but God does not work that way. The moment the Israelites crossed the river Jordan and ate of the produce of the land, Canaan land, manna ceased (Joshua 5:12). God is in the habit of humbling, testing, chastising and regulating whatever you get or receive from Him. He does nothing arbitrarily or haphazardly at all! The Israelites were humbled, tested, chastised, and their food and all they needed were regulated and rationed. This also is the way God treats those who intimately walk with Him—those who are unwaveringly committed and submissive to Him.

Of course, there would be a time of abundance or more than enough, when there would be no more lack or whatever, but the path to that level is what has been explained or shared here.
Peace!
