A common theme throughout the Book of Acts was that the people were with one accord. Something supernatural takes place when God’s people are with one accord.
When the disciples were staying in the upper room waiting for the promise, they were with one accord in prayer and supplication. Acts 1:14
On the Day of Pentecost they were all with one accord in one place. Acts 2:1. In Acts 4:24 after Peter and John were released from prison and told not to preach in the name of Jesus they raised their voice with one accord.
All through the Book of Acts we see that the people were with one accord and God moved mightily on their behalf. Lives were changed, the Kingdom of God was advanced and the people were blessed.
That word accord comes from the Greek “homothymadon”.
According to Strong’s Enhanced Dictionary it describes the uniqueness of the Christian community. It is a compound of two words meaning to “rush along” and “in unison.” The image is almost musical; a number of notes are sounded which, while different, harmonize in pitch and tone. As to instruments of a great concert under the direction of a concert master so the Holy Spirit blends together the lives of members of the Body of Christ.
The key ingredient to the move of the Spirit in the early church was the unity of the believers. They were of one heart, one mind, one passion. They were with one accord seeking the will of God in their lives. The church today should be doing no less.
