I have told you these things, so that in Me you may have [perfect] peace and confidence. In the world you have tribulation and trials and distress and frustration; but be of good cheer [take courage; be confident, certain, undaunted]! For I have overcome the world. [I have deprived it of power to harm you and have conquered it for you.]

John 16:33 AMPC
