Yes and no. When you read Amos you get a glimpse of a God who is angry with the Israelites and who is on the verge of punishing them for their apostasy (falling away from faith). However, to fully understand why God wanted to punish them is important to understanding God. He wasn't seeking to smite them because of their falling away from Him; instead He desired their hearts. His hope was that they would return to Him because He knew that their lives would be better if they were surrendered. God found no pleasure in their sacrifices because He knew where their hearts were. For this same reason He finds no pleasure in our sacrifices when our hearts aren't in order. He was ready to send them into exile with the hope that their loss of His benevolence would shock them into the reality of their situation. It was actually as an act of grace that God wanted to punish them because He wanted to get them back. Just like when parents punish their children. The loving parent punished his children because he knows the punishment will move them in the right direction. God was angry, but He wasn't smiting the Israelites out of anger; His ultimate goal was restoration. God desired relationship with them just as much as He does with us, and there are times when He has no other choice but to go to extreme measures to get our attention.
