God deserves praise and thanksgiving always. Now the Israelites lose faith even after Gods intervention to supply their needs. Did they really know God as a loving father and one who patiently led them to Canaan. Hardness of heart may imply that they were spiritually blinded by their flesh and self seeking ways. Did God break through this hardness for the future generation by allowing only children to enter. To bring God to such anger is horrible and to not fathom their Makers love is unbelievable. Did the children change their ways. God is always reaching out as we reach out to thank HIM for being a loving creator. HE asks for belief in HIM and obedience. If we rest in Him then we can hear what He desires from us on this earth:....ultimately to serve through love...
