Revere the Lord from our heart, it is not a custom!

2 Chronicles 12:1-16
Because they had been unfaithful to the Lord, Shishak king of Egypt attacked Jerusalem in the fifth year of King Rehoboam.
This is what the Lordsays, ‘You have abandoned me; therefore, I now abandon you to Shishak.
The leaders of Israel and the king humbled themselves and said, "The Lord is just."
They will, however, become subject to him, so that they may learn the difference between serving me and serving the kings of other lands.
Why?
The Lord is just, what evil had done, what consequence will come also.
When we humble ourselves for our sins, God gives us the opportunity to live, but however, God will let us learned the lesson through the suffering or pain, in order improve our spiritual life.
Live too easy may lead people abandon the Lord, forget the just of the Lord. Fear the Lord and humble ourselves is not a custom but revere God from heart. God should be put on the first priority in my life.
How?
Love the Lord with all my heart, all my soul and all my strength. It is not a living custom but humble myself. .
