1 Samuel 17:49 (NLT)
“Reaching into his shepherd’s bag and taking out a stone, he hurled it with his sling and hit the Philistine in the forehead. The stone sank in, and Goliath stumbled and fell face down on the ground.”
 
Be focused in your spiritual warfare. It is one thing to engage in battle, but it is something else to be focused on where you can make maximum impact. There are many places to plug in your energy. So don’t dissipate.
 
When David decided to fight Goliath, he knew he would not have a second chance to strike Goliath. So, while the giant was busy boasting and ranting, David was calculating and planning his strike.
 
Don’t waste energy on secondary issues. Leave empty talking to those light-headed brethren who think that talk is what changes things. We know that change only comes through spiritual engagement.
 
Look around you and make the right calculations. It’s called strategic thinking.

Ask yourself that critical question: “If you had one opportunity to remove that one obstacle on your way to God’s best for your life, what would you do?”
 
The first step in gaining momentum in your life and walk with God is to identify what to remove around you. Critical thinking means knowing what to do, when to do it, and how often to do it.
 
I repeat, David knew he had only one chance to hit Goliath, and he could not afford to miss. Likewise, don’t throw your energy into secondary things. Focus.
 
When David shot the stone at Goliath, it was with all the force he could muster. It was not a soft shot.
 
We need to do likewise. It is not enough to identify what needs to be hit. Focus must be accompanied by great effort. Yes, know the target, but hit it will all you’ve got.
 
Strategic focus can be summarized as aiming correctly at your most strategic target for maximum impact and doing so with all your resources. Please apply this to every endeavor in your spiritual pilgrimage.
