7And when the LORD saw that they humbled themselves, the word of the LORD came to Shemaiah, saying, They have humbled themselves; therefore I will not destroy them, but I will grant them some deliverance; and my wrath shall not be poured out upon Jerusalem by the hand of Shishak." (2 Chronicles 12: 6-7)
King Rehoboam struggled with pride throughout his reign. When things went well in his life, he strengthened himself and forsook God's law.
In reality, the moment that any king of Israel would forsake God's law, the people stopped offering animal sacrifices, and thus they were exposed to curses and condemnation, because without the shedding of blood, there is no remission of sin (Hebrews 9: 22).
Yet when they humbled themselves, then God turned away His wrath.
Most people believing that humbling oneself means screaming and crying and telling everyone how bad we are.
This verse says otherwise.
When the king and the rulers of Israel declared that God is righteous, then His wrath was turned.
The biggest issue for all of us is not that we get angry with God, or that we sin.
The one issue that upset God more than anything else is our insistence on our own efforts to right with God.
We need to depend on Him fully for all things, nothing less.
Apart from Jesus, we can do nothing (John 15: 5). He is our life, and we are dead without Him (Colossiasn 3: 1-4). Christ living in us is our hope of glory, and nothing else will suffice or surpass His gifts of righteousness and grace to us (Romans 5: 17)
Humility starts and ends with recognizing that God is good, God is great, that every good and perfect gift comes from Him, and in Him we find all things that we need.
Receive His righteousness (Matthew 6: 33), and all other things are added unto you!
