Power can be used in at least two ways: it can be unleashed, or it can be harnessed. The energy in ten gallons of gasoline, for instance, can be released explosively by dropping a lighted match into the can.
Or it can be channeled through the engine of a Datsun in a controlled burn and used to transport a person 350 miles.
Explosions are spectacular, but controlled burns have lasting effect, staying power.
The Holy Spirit works both ways. At Pentecost, he exploded on the scene; His presence was like "tongues of fire" (Acts 2:3>). Thousands were affected by one burst of God's power. But He also works through the church&md;the institution God began to tap the Holy Spirit's power for the long haul. Through worship, fellowship, and service, Christians are provided with staying power.
