In 1 John 4:4, who is the person "that is in the world"?

1. Satan

2. Jesus

3. your old sin nature

4. your Christian character

3.

Explanation:

it isn't Jesus because John is referencing that Jesus/God is greater than. Satan would be just a trick because if it was Satan, he would be directly referenced. Your christian character could be the answer, but looking into the context surrounding 1 John 4:4, your old sin nature makes more sense.
