1 Jn 2:1 My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous: The Lord Jesus Christ is not only the constant advocate for the believer that sins, but He is the advocate for the same one before they became a believer, and as they were enemies, dead in Trespasses and sins. In fact, He had already by His Death for them, reconciled them to God even while being enemies Rom 5:10 10 For if, when we were enemies[unbelievers], we were reconciled to God by the death of his Son, much more, being reconciled, we shall be saved by his life. What does advocate mean ? Its the Greek word paraklētos: summoned, called to one's side, esp. called to one's aid a) one who pleads another's cause before a judge, a pleader, counsel for defense, legal assistant, an advocate b) one who pleads another's cause with one, an intercessor 1) of Christ in his exaltation at God's right hand, pleading with God the Father for the pardon of our sins c) in the widest sense, a helper, succourer, aider, assistant 1) of the Holy Spirit destined to take the place of Christ with the apostles (after his ascension to the Father), to lead them to a deeper knowledge of the gospel truth, and give them divine strength needed to enable them to undergo trials and persecutions on behalf of the divine kingdom This advocacy work of Christ, being our defensive attorney, is an aspect of Him being also an Intercessor for those He died for Rom 8:33-34 33 Who shall lay any thing to the charge of God's elect? It is God that justifieth. 34 Who is he that condemneth? It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us. He is being an advocate,m and intercessor for anyone He died for of the Elect. This Work of His is based solely on His Death for them, and not their Faith in Him, even though that shall come to pass; However He was their Advocate before they believed as Per Jn 17:20 indicates 20 Neither pray I for these alone, but for them also which shall believe on me through their word; He was praying for those in the present, who shall yet believe in the future, so they were still unbelievers ! Its not if they shall believe either, and neither did He suspend His intercessory prayer for them until after they believe ! Those Jesus Christ died for are never condemned, even while they are in sin and unbelief !
