We want God's Kingdom to come. But victory has already been won at the cross. The devil is defeated and salvation has come. Still, patience is needed. God is working out His will.
Opportunity is still available for others to be saved.
When that number is complete, He will return and all evil will be removed. If we could, most of us would choose life to be all gain. None of us like the negative. However, in this life we all go through different experiences. And a time to laugh and a time to mourn.
