Christians who get screwed over by God’s plan should rejoice, for they are part of God’s plan. Let’s say, for example, a racist cuntknuckle walks into an historic black church and murders nine innocent people. Hypothetically, of course. The victimized church and other Christians should rejoice in the knowledge that it was all part of God’s plan. They should celebrate and shout “Glory to God for murdering my sister and my dad!” “Thank you, Lord, for bringing death, destruction and agony within Your plan!” “Praise Jesus, this will be totally worth it when I die some day!”
If they were to cry and be upset, that would be denying the wisdom and glory of God’s wonderful plan. God doesn’t like it when you deny His plan. He might strike down upon you with great wrath and furious vengeance for questioning His wisdom. So, just to be safe, don’t be upset when tragedy strikes. That would just be disrespectful.
