Why was this so apparent with the Early Church? As you will remember, the Word of God was central to everything the church did from the beginning. The first preaching by Peter on the Day of Pentecost was full of references to the Old Testament which confirmed what God was doing at the moment. In that way, the Word of God must be the foundation for all we do and the reason God brings results, equaling expansion and multiplication.
Scripture clearly indicates what happens when the Word is not central. There was corruption in the house of the Lord during this time of Eli because “the Word of the Lord was rare in those days” (1 Samuel 3:1). The spiritual condition in Corinth was so low that Paul “could not address [them] as spiritual people” (1 Corinthians 3:1). When the Word of God governs the life and ministry of the people of God, conditions like this are prevented. The most powerful remedy to such conditions was what “is written” in the Word of God (1:19; 2:9; etc.).
It should not surprise us to see the Word of God increase where it is faithfully relied on for church life and the expansion of the gospel. As we see from Acts 6:7, the most unexpected people become “obedient to the faith” when the Word is allowed to powerfully work in and through us.
