John 16:31-33

Jesus answered them, Do you now believe? [Do you believe it at last?] But take notice, the hour is coming, and it has arrived, when you will all be dispersed and scattered, every man to his own home, leaving Me alone. Yet I am not alone, because the Father is with Me. 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.]
