Proverbs 24:5-6 – A wise man is mightier than a strong man, and a man of knowledge is more powerful than a strong man.  So don’t go to war without wise guidance; victory depends on having many counselors.
Knowing your adversary’s strategies is the first step before engaging in battle.  The objective to find out the bigger picture, knowing what to anticipate, is part of wisdom.  It is wise to know who you are going up against before rushing into battle.  It is also wise to not go it alone. 
Before a mixed martial arts fight, both fighters study their opponent.  They watch for his opponent’s strengths, how he moves, and also looks for his weak areas so he can capitalize on them during the fight.  He has coaches and other team mates who can guide him into making the best possible game plan. 
Moses had seventy men, David was accompanied by the mighty men, and Jesus had twelve disciples.  All three of these leaders did not complete their objectives without the guidance of others.  Jesus is the exception, but He demonstrated this as an example for us.
These stories should show us we need our brothers and sisters to grow spiritually.  We need each other to succeed in our current battles, and to fend off the attacks of the devil.  Do not be deceived when you are told you can go it alone.  Doing so would not be wise.
