Everyone will experience sorrow and trials at one point

Our first spiritual war begins when we decide to keep the commandments of God and share the testimony of Jesus Christ but there is an assured victory. St. John 16:33 NLT 

 I have told you all this so that you may have peace in me. Here on earth you will have many trials and sorrows. But take heart, because I have overcome the world." 

Rev. 12:11 KJV. And they overcame him by the blood of the Lamb, and by the word of their testimony; and they loved not their lives unto the death.
