John 16:33

 You’re referring to a statement by Jesus from the Bible, specifically John 16:33.

A common translation reads:

“I have told you these things, so that in me you may have peace. In this world you will have trouble. But take courage! I have overcome the world.”

This comes near the end of Jesus’ farewell teaching to his disciples before his arrest. The phrase “overcome/conquered the world” is usually understood to mean that he has overcome the forces of fear, sin, suffering, and separation from God—not that worldly hardship disappears. The line starts by acknowledging difficulty (“you will have trouble”) and then pairs it with reassurance (“take courage”).

It’s interesting alongside Gita 12.20 because both passages speak to steadiness and faith amid difficulty, though from different religious frameworks: the Gita emphasizes devoted living and inner equanimity, while John 16:33 emphasizes courage and peace through trust in Christ.

If you want, I can also  show the original Greek wording of “I have overcome the world” or  compare it more directly with the Gita passage.
