Every unsaved person will have windows of opportunities when he becomes most receptive to the gospel of Christ. The Devil works hard to keep people in darkness and will distract them by every means necessary (i.e., the death of a loved one, a crying child, a ringing phone, busyness, etc.). The salvation of a soul involves a spiritual battle that can only be won by the Lord’s intervention. There is a window of time when the lost are most receptive to the gospel, likewise suggesting only a window of opportunity for the saved to speak for Christ. This is the very reason the apostle Paul stressed the importance of the saints of God beseeching the Lord to open to them a door of utterance (Ephesians 6:19).
The powers demonstrated by the apostles have consumed many Bible teachers who fail to grasp the place and purpose of those powers. These teachers instruct believers to seek the same power that was bestowed upon Peter and Paul and the other apostles. Careful Bible study demonstrates that the motive in this teaching is misplaced. The power given to the apostles was given for the purpose of assisting them in telling a lost and dying world about a risen Saviour. Much of the modern teaching centers upon pride and encourages a selfish Christianity. The biblical power given to the apostles was meant to strengthen their witness to others, not simply to be a self-serving instrument. Modern Christianity focuses on self, while biblical Christianity focuses on the Saviour and others.
