Beloved, we are [even here and] now children of God, and it is not yet made clear what we will be [after His coming]. We know that when He comes and is revealed, we will [as His children] be like Him, because we will see Him just as He is [in all His glory].

No one who is born of God [deliberately, knowingly, and habitually] practices sin, because God’s seed [His principle of life, the essence of His righteous character] remains [permanently] in him [who is born again—who is reborn from above—spiritually transformed, renewed, and set apart for His purpose]; and he [who is born again] cannot habitually [live a life characterized by] sin, because he is born of God and longs to please Him.

By this the children of God and the children of the devil are clearly identified: anyone who does not practice righteousness [who does not seek God’s will in thought, action, and purpose] is not of God, nor is the one who does not [unselfishly] love his [believing] brother.

My little children (believers, dear ones), I am writing you these things so that you will not sin and violate God’s law. And if anyone sins, we have an Advocate [who will intercede for us] with the Father: Jesus Christ the righteous [the upright, the just One, who conforms to the Father’s will in every way—purpose, thought, and action].

whenever our heart convicts us [in guilt]; for God is greater than our heart and He knows all things [nothing is hidden from Him because we are in His hands].

Everyone who practices sin also practices lawlessness; and sin is lawlessness [ignoring God’s law by action or neglect or by tolerating wrongdoing—being unrestrained by His commands and His will].
