Our faith overcomes the world... that is what the verse says... in context it is talking about keeping the commandments and loves others. I believe the commandments spoken of are the two that Christ gave as He walked on the earth...
Our faith is made strong but loving the Lord with all our heart, soul, and mind, and loving others as we love ourselves. Then the faith we have helps us have victory to overcome the world.
We can have minor victories through out our lives here on earth, but the ultimate victory is over death and Satan in the end. I get to live eternally with my Lord and Savior because I have faith in His victory on the cross and death. That is the ultimate VICTORY!
Thanks for reading. God Bless You All!
