John 16: 7But I tell you the truth: It is for your good that I am going away. Unless I go away, the Counselor will not come to you; but if I go, I will send him to you. 8When he comes, he will convict the world of guilt in regard to sin and righteousness and judgment: 9in regard to sin, because men do not believe in me; 10in regard to righteousness, because I am going to the Father, where you can see me no longer;

Conviction of sin is for the world. Once we have accepted that Jesus died on the cross for our sins and erased our sin debt, we should no longer entertain guilt.

Conviction of righteousness is for believers. As believers we are to strive to imitate Jesus. So, through the grace, or the empowerment, of God we imitate Christ to bring glory to God and draw more people to an abundant, eternal life. The Spirit convicts us of opportunities to be righteous also, because our righteous obedience improves the abundance of our lives.
