Paul was a great prayer warrior and was always interceding for others.  Here are three passages having to do with Paul’s intercession. Then please take note of the three things I have observed from Paul about what intercession is:

Romans 1:9-10

For God, whom I serve in my spirit in the preaching of the gospel of His Son, is my witness as to how unceasingly I make mention of you, 10 always in my prayers making request, if perhaps now at last by the will of God I may succeed in coming to you.

Colossians 1:3-5

We give thanks to God, the Father of our Lord Jesus Christ, praying always for you, 4 since we heard of your faith in Christ Jesus and the love which you have for all the saints;

Philippians 1:3-11

I thank my God in all my remembrance of you, 4 always offering prayer with joy…
