1 João 3:2
Therefore we live as children of God even in this present life, sanctifying ourselves by virtue and striving toward the likeness of something even better. Encouraged by this, we shall be fashioned according to the brightness of the resurrection, when we shall see him, insofar as that is possible, as he is. — CATENA
1 João 3:9
John did not say this with respect to the existence of sin in our lives, as if our nature were covered with impassibility. Rather he means that insofar as someone who is born of God retains the grace of his new birth he cannot sin in the way he behaves. And the reason for this is that God's seed dwells in him. What is this seed of God which dwells in believers? What else but the indwelling of the Holy Spirit, by which we have been born again? This presence never leaves us. — CATENA
