Thank you for your prayers.
Christ intercedes for us:
Rom 8:34 "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."
Rom 8:27 "And he that searcheth the hearts knoweth what is the mind of the Spirit, because he maketh intercession for the saints according to the will of God."
Heb 7:25 "Wherefore he is able also to save them to the uttermost that come unto God by him, seeing he ever liveth to make intercession for them."
Isa 53:12 "Therefore will I divide him a portion with the great, and he shall divide the spoil with the strong; because he hath poured out his soul unto death: and he was numbered with the transgressors; and he bare the sin of many, and made intercession for the transgressors."
John 17:20 "Neither pray I for these alone, but for them also which shall believe on me through their word"
So, I am thinking that prayer is still an effectual work.
The effectual fervent prayer of a righteous man availeth much (James 5:16).
