If you ever wonder what you should pray about for others, always keep in mind that people need the Spirit-filled, Spirit-led life. The Spirit of God is the one who brings us through this life successfully. That which the Holy Spirit does for us is centered around what we do for the kingdom of God. Paul prayed for people to understand who they are in Christ, so that they will bear fruit and be grateful to God for how good he is, as they finish the race strong.
For this reason, since the day we heard about you, we have not stopped praying for you. We continually ask God to fill you with the knowledge of his will through all the wisdom and understanding that the Spirit gives, so that you may live a life worthy of the Lord and please him in every way: bearing fruit in every good work, growing in the knowledge of God, being strengthened with all power according to his glorious might so that you may have great endurance and patience and giving joyful thanks to the Father, who has qualified you to share in the inheritance of his holy people in the kingdom of light. - Colossians 1:9-12
