1 John 3:3-6 New King James Version (NKJV)

3. And everyone who has this hope in Him purifies himself, just as He is pure.

4. Whoever commits sin also commits lawlessness, and sin is lawlessness.

5. And you know that He was manifested to take away our sins, and in Him there is no sin.

6. Whoever abides in Him does not sin. Whoever sins has neither seen Him nor known Him.
