Man does not change in order to be saved, but true salvation always brings about an evident change in the life of the new believer. Perhaps the change is less noticeable in some new believers and more noticeable in others; however, no change means no salvation. The change is not always an immediate outward change because it involves a change of the inward nature. A person who trusts Christ for salvation becomes a new creature (Galatians 6:15). It might be best to consider how this could be likened to a dog (Matthew 15:26-27) becoming a sheep (John 10:16). A new man now dwells within the new Christian to help combat and defeat the old sinful nature (Ephesians 4:22-24). Salvation is not merely the turning over of a new leaf; it is a new birth (John 3:3) where one is passed from spiritual death to spiritual life (John 5:24).
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.
