Having a pure life requires constant care. In 1 Timothy 4:16 Paul warns Timothy, Watch your life and doctrine closely. Persevere in them, because if you do, you will save both yourself and your hearers. We must be constantly on guard to watch against sin that can ultimately destroy us. We must also watch what we believe just as carefully and not allow society to dictate what is right versus wrong. When we look to God as our compass, He will never lead us down the wrong path.
