Yes and that 'participating' can take the form of 'striving' and 'working' hopefully without being called legalistic.
But by the grace of God I am what I am: and his grace which was bestowed upon me was not in vain; but I laboured more abundantly than they all: yet not I, but the grace of God which was with me.
(1Co 15:10)
Amen...whether this "striving and working" is legalistic or through the grace of God working through us....only the Lord can answer that one.
Those works will be judged when they go through the fire that Paul talks about in Corinthians.
Unless the Lord build the house - they labor in vain who build it.
I do like your scripture that shows it was not Paul in his flesh/self-effort doing it ( NOT "I" said Paul )...but it was the grace of God which was with him doing these labors through him. Great scripture!
