What happens if we refuse to change? Remember the vacuum tube? The electronics revolution of the 20th century possibly began with the vacuum tube. The first general-purpose computer, the "Eniac" was built in 1946 with 17,000 vacuum tubes. It took 1800 square feet of floor space and consumed 150 kW of power. Although there is still a niche market for vacuum tubes, the industry has largely died. You can still buy them from a small company in Memphis, but they no longer dominate the market and companies that refused to change died. How dangerous is refusing to change? In John 1:6-28 John prepared the way for massive changes in God’s covenant relationship with humanity. Throughout church history change has always been difficult. The Gospel does not change, but the culture does and churches must adapt or die.
