As Jehovah's people, we don't have a breaking point. Jehovah understands our capabilities and limitations so much better than we do, therefore we have every assurance that we handle anything that comes our way with His help.
How could one not love such a wonderful, perfect God? He is so good to both the righteous and the wicked and both benefit from HIS love. But, It's every persons choice whether to love HIM in return. Sadly, the majority of people don't.
