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).
As opportunities present themselves, we ought to “do good” unto others. Scripturally speaking, we have a basic duty to help “all men,” but our foremost responsibility should be directed toward those “who are of the household of faith.” Regardless of our heart’s desire, the Lord knows there are times when we cannot help those in need. This fact should never be used as an excuse when we have a genuine opportunity, as the good that we might do to others does not always merely involve financial help. Acts chapter 3 offers an example of Peter and John who were faced with such a situation. Peter responded, “Silver and gold have I none; but such as I have give I thee” (Acts 3:6). Where these men lacked any monetary opportunity to help the lame man, they fulfilled their responsibility by imparting help in the way that God had especially enabled them.
