I have discovered another truth about suffering, it makes us more aware of sin, both of our sin and of the sins of those closest to us. As different people endure suffering, some lean more towards recognizing their own sin and others focus on the sin of family and others close to them. As I have endured suffering, I believe it is important to achieve balance between the two. We must be aware of and repent of our own sin, but we must also recognize sin in others. If we must make a mistake by leaning more one way than the other, it is good to focus a little more on our own sin.
Suffering also provides glimpses of loving-kindness. It may only be a glimpse, but we hear a kind word or see a kind deed, and we are comforted by the moment of loving-kindness.
