The bible has all the answers to any question that can be raised by the entire universe. In the book of John 16:33 our Lord Jesus Christ made us to understand that it is only in him that we can find peace. In the world full of tribulations, he reminds us to be of good cheer because he have overcome the world and anyone who trust in him will be able to overcome the world through his power.
As Christians, we must encounter tribulations provided we are living on earth. We are in the world without peace, the only things in the world is problems, tribulations, foolishness, illusions etc. Our Lord Jesus Christ made us to understand in this teaching that if only we will be calm and peaceful amidst the problems and tribulations of the world, we will be able to conquer the world because he is solidly behind us.
God bless you all 🙏
