2 Chronicles 35- Ezra 10

The one thing that stood out to me was the prayer on Ezra 9 : 5-15. This is the type of intercessory prayers we still need today.  Vs 6 says "our  iniquities are increased over our heads, and our trespass is grown up unto the heavens"

This speaks volumes of how the amount of disobedience of God's commandments and the necessity of repentance  

Lesson -  You cant rebuild properly with unrepented  sins, transgressions and iniquities.  We need to repent,  renounce of disobedience and recommit  to God with obedience.
