Rejoice in the Lord always. That’s the command. How do we rejoice when we suffer? There’s always a reason to rejoice, despite any circumstance. The Bible tells us that God is love, that He’s a good father, that He’s watching over us, always with us. The Bible also tells that God has the ability to control all of creation, including Satan. If we can hold onto these truths, then we have a reason to rejoice and to be thankful. We can rejoice knowing that God is using all things, even the horrible, awful things, together for our good; He has our best in mind. If you really believe that God is your perfectly loving and caring Father who has everything under control, then you can be thankful and rejoice even in the darkest of circumstances.
