Scripture Text:  "Then Saul dressed David in his [Saul's] own tunic.  He put a coat of armor on him and a bronze helmet on his head.  David fastened on his sword over the tunic and tried walking around because he was not used to them.  "I can not go in these," he said to Saul, "because I am not used to them."  So he took them off.  THen he took his staff in his hand, chose five smooth stones from th estream, put them in the pouch of his shepherd's bag and, with his sling in his hand, approached the Philistine.  David said to the Philistine, "You come against me with sword and spear and javelin, but I come against you in the name of the Lord Almighty, the God of the armies of Israel, whom you have defied."  (1 Samuel 17:38-45)
Many people recognize this passage of Scripture as an excerpt from the story of David and Goliath.  Scholars tell us that David was perhaps just twelve or thirteen years old when this event took place in his life. We also know that no one in the army of Israel was willing to face the warrior, Goliath.  David faced this challenge with faith, and slew the nine foot tall Philistine with one smooth stone and a sling. 
There are some very striking details about this story that we can apply to our own faith.  Primarily, it is God and not man who equips us for the tasks we've been assigned.  Surely the king meant well when he offered his armor to David.  It was his intent to protect the young boy.  But the Saul's equipment was burdensome to David.  It didn't fit David at all!  He couldn't even walk in the stuff.  Rather than try to fight with Saul's armor, David put his faith in God and used what God had given him.  He didn't need the fancy breast plate and heavy sword.  That was Saul's to use.  David didn't put his faith in Saul's armor.  He believed in God and accomplished a legendary feat using what God had provided him...a sling and a stone.  That's an important lesson for life and for ministry.  Often we sense that God has asked us to do something big.  But we may not be confident that we have what it takes to achieve success.  So we try to function in someone else's anointing.  But the same Holy Spirit that is in the person you are imitating is also in you.  God doesn't want you to try serving him in another man's anointing.  He wants to personally be your covering and your empowerment, to accomplish His tasks in your own anointing that only He can give you.
Secondly, serving God doesn't always have to be uncomfortable.  How often have I heard the cliche, "This is so far outside of my comfort-zone, it has to be God."  No it doesn't!  It might be, but it doesn't have to be.  God has gifted and qualified each person to serve Him in unique ways.  It's kind of like the Holiday Inn Express commercials.  Just because you stayed in a Holiday Inn Express last night does not qualify you to perform brain surgery the next morning.  That's ludicrous!  Likewise, being called to serve the Lord does not mean that life has to be miserably uncomfortable.  Sometimes ministry is comfortable because it just fits!
Thirdly, as a church, it's important that we not try to function in another church's anointing.  God has a special calling to every church where ever that church may be.  Whatever is happening in your church is happening because God has tooled your church and brought the right people at the right time for His purpose.  The church down the street, or in another state, or in another country may be experiencing great things in the Spirit.  Good for them!  But that particular happening may not be what God has called or gifted your church for right now.  Beware that replicating another church's ministry could be as dangerous as going to battle in misfitted armor.  Do what fits for your church in your community.  God will bless it, and do even greater things than your church ever dreamed!
The point is, do what you know is right for you.  Don't imitate another man's anointing.  Don't replicate someone else's ministry.  Walk in your own anointing.  It doesn't matter that it's not as flashy, not as heavy, or not as complete as you want it to be.  Use what God has given you where God has placed you, and He'll accomplish the great task through you.
