The human condition is what it is. Some of us live in squalor. Some of us are subjected to violence. While others live in wealth and safety.
This is NOT God^s doing.
Calvinists say that God is to blame. (I guess Habakkuk was a Calvinist.) But all God did was give man the ability to make decisions and the life to effect his plans.
The blame for the fall is on man. The blame for the disease, violence and death - the human condition - is on man.
God is our Saviour, our Healer and our Deliverer in Christ Jesus. But Habakkuk did not know this.
