As children, at times we were foolish because of a lack of wisdom, but as we mature in understand of knowledge, we hopefully become wiser and are able to make better decisions. As believers, we should be growing in the same manner. In 2 Timothy 2:22 Paul writes, Flee the evil desires of youth, and pursue righteousness, faith, love and peace, along with those who call on the Lord out of a pure heart. While running away can sometimes be called cowardly, wisdom dictates that we make wise choices which may require running away from evil.
