1 John 3:1

"How great is the love the Father has lavished on us, that we should be called children of God! And that is what we are! The reason the world does not know us is that it did not know him." NIV translation

This is one of the most beautiful and profound verses in all of the Bible as we are told of our relationship with God. We also see that there is a big difference between us and the world.

1 John 3:2

"Dear friends, now we are children of God, and what we will be has not yet been made known. But we know that when he appears, we shall be like him, for we shall see him as he is." NIV translation

Many are living and hoping to be saved but, as we see here, we are saved today and are children of God through the blood of Jesus Christ. We are also being saved as we are being transformed to be more like Christ in our thoughts and actions. We will be saved in the future when Jesus comes back and takes us out of this sinful world. At that point, we will finally see Him as He is and we will see us as He designed us to be without any effects from sin.

1 John 3:3

"Everyone who has this hope in him purifies himself, just as he is pure." NIV translation

When we come to faith in Jesus and realize how holy and pure He is, we want to be pure out of our love for Him. We are no longer ruled by sin as the focus of our life is changed.

1 John 3:4 & 5

"Everyone who sins breaks the law; in fact, sin is lawlessness. But you know that he appeared so that he might take away our sins. And in him is no sin." NIV translation

Sin is anything that is not in the will of God. We all are not in the will of God 100% of the time as we battle our own wants that are contrary to His will. But, Jesus who had no sin came to be the perfect sacrifice for our sins and through Him our sins are taken away.
