God intended the world to be a good place, and he suffers whenever people are poor, sick, weak and suffering. All this came into the world because of our selfish and sinful choices, starting with the first people. We can make a true difference by sharing whatever we have with others. God needs you to make the world a better place!
God created you to be happy (Phil 4:4). The suffering of this life is not the end. Thanks to Jesus’ sacrifice on the cross a better life is waiting in heaven for those who are suffering now. That is a good reason to be happy, even when not everything is perfect yet. None of us personally is perfect: we all need conversion, turning back to God and the people we hurt time and time again.
