John 16: 33 Amplified Bible
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].
You are not alone because Jesus is with you and because He is with you, you can have supreme confidence and assurance that the world has no power over you. Jesus has defeated the power of the world and taken away any and all power that it had over you. Jesus has overcome the power of the devil and His ability to harm you.
Jesus tells us that the world has trials, tribulation, etc. but that we are not to be discouraged by the problems of the world because he has already defeated them for us. We are not of the world (John 17: 14) so we don’t have to partake of the world’s trouble. We are of Jesus, so we partake in His perfect peace. He says, “Be of good cheer.” In other words, cheer up. “Don’t worry; be happy” like the song says.
Here is the long and short of it. The devil comes to steal, kill, and destroy (John 10: 10). He is going to try to spread strife, destruction, anguish and every other sort of torment. But the thing is, we do not have to participate in all that. Jesus defeated Satan and all his schemes for us. The people in the world just have to fight through all of that the best way they can. You do not. One truly great thing about being a Christian is that all that junk has already been conquered for us. I am not saying that Satan won’t try to get at you, but you don’t have to succumb to his shenanigans. You really don’t even have to fight him because he is already a defeated foe. You do, however, need to start understanding your victory in Jesus so that you don’t allow the devil to deceive you into thinking that you are fair game for him. You have been purchased by the blood of Jesus and have the victory over every scheme of the devil and all the suffering of this world. So, the next time the devil tries to attack you or the distress of this world starts to get to you, remind yourself that you are not of this world and its problems but rather that Jesus has purchased you out of the world and given you victory over all of its problems. Reach out with your heart to the comfort of Jesus.
