The strength of a chain is determined by the weakest link.
When a team contains a stupid, this stupid determines the performance of the team.
But Christ overcomes the sin of the world. It is similar to as if the strength of a chain were determined by the strongest not weakest link.
It may be very hard to believe that Christ can overcome all sinners and make the whole system effective. But He has demonstrated that he can resurrect even if sinners kill Him.
This is the glory of Christ.
