When you are a leader such as Thembeka, you need to have contentment and peace that is from Christ in order to have a spiritual discernment. It is our joyful work to help each others to achieve that.
He humbled you, causing you to hunger and then feeding you with manna, which neither you nor your ancestors had known, to teach you that man does not live on bread alone but on every word that comes from the mouth of the Lord .
Deuteronomy 8:2-3
From Helen
Why did God made the Israelities wonder in the wilderness for 40years?
It says in the previous verse
“Remember how the Lord your God led you all the way in the wilderness these forty years, to humble and test you in order to know what was in your heart, whether or not you would keep his commands.”
God humbled them to rely on him instead of themselves.
