Moreover the LORD your God will circumcise your heart and the heart of your descendants, to love the LORD your God with all your heart and with all your soul, so that you may live. (Deuteronomy 30:6)
(Tim) In 1Corinthians 3:4 ff. the Apostle Paul is rebuking the Corinthians' party spirit. Different factions of the congregation were lined up behind this or that minister of the Gospel using this or that man to get a leg up on their opponents. So the Apostle Paul has the dicey job of defending his own apostolic authority and doctrine, honoring the beautiful feet of ministers of the Word while also opposing the hero worship at the heart of the Corinthian division.
He ends up saying, on the one hand, that ministers of the Gospel are the means by which God's people come to faith in Jesus Christ; but on the other hand, that ministers of the Gospel are nothing. So it's both ministers are God's chosen instrument and ministers are nothing.
For when one says, “I am of Paul,” and another, “I am of Apollos,” are you not mere men?
What then is Apollos? And what is Paul? Servants through whom you believed, even as the Lord gave opportunity to each one. I planted, Apollos watered, but God was causing the growth. So then neither the one who plants nor the one who waters is anything, but God who causes the growth. (1 Corinthians 3:4-7)
See the careful footwork?
Ministers are "servants through whom (the Corinthians) believed." Ministers are servants who "planted" and "watered as "God caused the growth." And...
Ministers are not anything (which is another way of saying ministers are nothing).
Our hearts are filled with love for the ministers of the Gospel who planted and watered so we might hear and believe the Good News, and be saved. But immediately, the faithful minister, the Apostle Paul, the Holy Spirit reminds us ministers are nothing at all. It is always God Who gives us the opportunity and causes the growth.
Now stick with me, here. I know it all seems so very obvious as not to need any comment, but follow the logic here, carefully.
