We may pray for others as Paul interceded for the Colossians.
“For this reason, since the day we heard it, we have not ceased praying for you and asking that you may be filled with the knowledge of God’s will in all spiritual wisdom and understanding, so that you may lead lives worthy of the Lord, fully pleasing to him, as you bear fruit in every good work and as you grow in the knowledge of God. May you be made strong with all the strength that comes from his glorious power, and may you be prepared to endure everything with patience, while joyfully giving thanks to the Father, who has enabled you to share in the inheritance of the saints in the light.” (Col 1:9-12)
Paul didn’t know how to pray as he should, but he told us to “pray at all times in the Spirit”.
“Pray in the Spirit at all times in every prayer and supplication. To that end keep alert and always persevere in supplication for all the saints.” (Ephesians 6:18)
The Spirit operates in several ways according to the article Holy Spirit:
•It prepares men through grace to draw them to Christ.
•It manifests the Risen Lord to men by spreading his word and helping them to understand the mysteries of the faith.
•It makes Christ present, especially in the Eucharist.
•It brings men into closeness with God.
The Holy Spirit is continuously helping us in our prayers.
“Likewise the Spirit helps us in our weakness; for we do not know how to pray as we ought, but that very Spirit intercedes with sighs too deep for words. And God, who searches the heart, knows what is the mind of the Spirit, because the Spirit intercedes for the saints according to the will of God.” (Rom 8:26-27)
Christ is the Intercessor between Humanity and the Almighty Father.
“For through him both of us have access in one Spirit to the Father.” (Ephesians 2:18)
“Who is to condemn? It is Christ Jesus, who died, yes, who was raised, who is at the right hand of God, who indeed intercedes for us.” (Romans 8:34)
“Consequently he is able for all time to save those who approach God through him, since he always lives to make intercession for them.” (Hebrews 7:25)
“For Christ did not enter a sanctuary made by human hands, a mere copy of the true one, but he entered into heaven itself, now to appear in the presence of God on our behalf.” (Hebrew 9:24)
