I'll let you in on a secret, Jesus knew who he was. He said he was the son of God, it was correct. We are all sons & daughters of God. More precisely, facets or aspects of God. We are One with God, not separate from God as many religions teach.
There is no "we" who are all God's children.
Everyone who sins practices lawlessness. Sin, in fact, is lawlessness. But, as you know, Christ appeared to do away with sins, and in Him there is no sin. No one who remains in Him keeps on sinning. No one who continues to sin has ever seen Him and does not known Him.
My children, do not be misled: The one who does what is right is righteous, just as Christ is righteous. The one who sins is of the devil, because the devil has been a sinner from the beginning. This is why the Son of God was revealed, to destroy the works of the devil.
Anyone born of God does not sin, because the divine seed abides in him; he cannot continue to sin, because he has been born of God. By this the children of God are distinguished from the children of the devil: No one who does not do what is right is a child of of God, nor is anyone who does not love his brother.
