Summary: John wants us to know that God’s promise of eternal life comes with a guarantee of sinlessness. Sin will be done away with altogether. And at that point, we will not only be seen as righteous before God because of what Christ has done for us, we will actually be righteous. In every way. Our old sin natures will be done away with once and for all. And the point of all this, is that we should live with the promise of future sinlessness in mind.
