Break Down of 2 Chronicles 7:14

2 Chronicles 7:14 KJV
If my people, which are called by my name, shall humble themselves, and pray, and seek my face, and turn from their wicked ways; then will I hear from heaven, and will forgive their sin, and will heal their land.

Its really about the order of events..
Before you pray or even seek the face of God, you must humble yourself . Humility is becoming selfless. You have to forget about yourself and your situation before you come before God.
Then you must pray... prayer is speaking to God.
Then you must seek His face.
When one has to come before a king, in order to seek him, he or she must first get into the palace.
The bible says in Psalms 24 to enter His courts with thanksgiving and into His courts with praise.
Turn from our wicked ways: during prayer, you repent. But after seeking the Face of God and entering into His presence....you will never be the same. Thus, you must turn from the wickedness that was done prior to prayer.
Then will the Lord hear from heaven, only after you become humble, casting down pride, only after you genuinely speak to Him and come before His presence like the debtor went before the king. The king had mercy upon him, just as your Father in heaven will have mercy upon you. Which is what's next: He'll forgive your sin.
And then He'll heal your land. The land is cursed after the disobedience.
Once you obey, the land is healed.
