"Now it came to pass, when Rehoboam had established the kingdom and had strengthened himself, that he forsook the law of the LORD, and all Israel along with him." (2 Chronicles 12:1)
Isn't that what happens most of the times? We fight, fast, pray early dawns, and when we get what we wanted we no longer seek God with the same intensity and position. You see that Rehoboam not only turned away from God but he led all the people to turn away from Him. When we take the wrong attitudes, we make others mess up. Do not forget: We are the mirrors to the members.
"Thus says the LORD: ‘You have forsaken Me, and therefore I also have left you in the hand of Shishak." (2 Chronicles 12:5) Leaving God isn't just leaving church, it involves SO much more! For example, it's to stop trusting in Him when facing a big problem, its also reaching the 'self-sufficient' status, or achieving financial blessings and stop trusting in God because we depend on our own achievements. When we stop seeking God we automatically drift away and lose his anointing and protection. This is what happened to Rehoboam. But, I have good news: he humbled himself! If we humble ourselves and recognize that we're nothing, the response of our merciful God will be immediate!
"So the leaders of Israel and the king humbled themselves; and they said, "The LORD is righteous. Now 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. My wrath shall not be poured out on Jerusalem by the hand of Shishak. Nevertheless they will be his servants, that they may distinguish My service from the service of the kingdoms of the nations." (2 Chronicles 12:6-8)
This difference exists in each one of us, when we humiliate ourselves before God and serve Him with sincerity. God allowed the devil (Through Shishak) to touch some things (verse 9). In the end the person will reap what he plants; but when The Word of God finds a heart in good soil, the fruits will be obvious! So then, lets be humble! Remember, God is not blind to your problems.
"When he humbled himself, the wrath of the LORD turned from him, so as not to destroy him completely; and things also went well in Judah."
