Since his suffering came from his unselfish loving, it follows that we must try to discern the causes of our suffering. Not all suffering comes from loving. Indeed, it is far more likely to come from frustration or disappointment because we cannot have everything we want. To walk with the suffering Christ is to feel the pain that inevitably accompanies the kind of love that sacrifices for the sake of others. Good parents do this for their children and good children love and obey their parents, even when it means giving up something they want.
Good teachers sacrifice for their students also.
The amazing thing about this kind of loving is that, though it is often very painful, there is a joy in it also. This should not surprise us because, after all, we were created to become free and then to convert our freedom into loving service. Nothing is more compatible with our true nature as God's children and nothing is finally more successful than the resurrection victory that follows such generous and faithful concern for others.
