Peter Dietsch of Providence Presbyterian Church in Midland, penned an outstanding piece on what it means to be an "ordinary means of grace church." From the post:
"The ‘means of grace’ refers to the concept that God uses particular means (methods or modes of communication) to communicate or give His grace to His people. When we speak of the ordinary means of grace, we are speaking specifically of ‘the word, sacraments, and prayer.’ This idea and the language used to express it comes from the Reformed confessions of the 16th and 17th centuries. For instance, the Westminster Shorter Catechism, question 88, says this:
Q. What are the outward means whereby Christ communicateth to us the benefits of redemption?
A. The outward and ordinary means whereby Christ communicateth to us the benefits of redemption, are his ordinances, especially the word, sacraments, and prayer; all which are made effectual to the elect for salvation.
These are the things that Christ has instructed us to use as His church to receive His grace. Of course, God is able to work through any means He wishes – or even apart from means, should He desire to do so – but the Catechism is here summarizing the teaching of Scripture that the ordinary things that God uses to bestow His grace, bless His people, bring them to faith and grow them in that faith are: the word, sacraments, and prayer.
At one time, the Lord even used a donkey (!) as a means of communication (Numbers 22; 2 Peter 2:16); however, it’s certainly not ordinary. Simply because God chose to speak through a donkey at one point in history, it does not mean that we all need to start listening to donkeys or keep one in our back yard just in case God desires to do it again. Instead, we attend to the instruction which He has given us in the Scriptures and pursue God’s grace through the ordinary means that He has given us: the ministry of the word, the sacraments, and prayer."
