Colossians 1 1:24
I am doing a study of Colossians and have an essay to write on 1:24 and its meaning.
I now rejoice in my sufferings for you, and fill up in my flesh what is lacking in the afflictions of Christ, for the sake of His body, which is the church.
If any of you know where I can find a good commentary on it, or have any ideas yourself, your help would be highly appreciated.

I like the Geneva Study Bible and Matthew Henry personally.
