God has equipped us with what we need to achieve the victory

Judges 3:31
New International Version (NIV)
31 After Ehud came Shamgar son of Anath, who struck down six hundred Philistines with an oxgoad. He too saved Israel.

Judges 15:14-15
New International Version (NIV)
14 As he approached Lehi, the Philistines came toward him shouting. The Spirit of the Lord came powerfully upon him. The ropes on his arms became like charred flax, and the bindings dropped from his hands. 15 Finding a fresh jawbone of a donkey, he grabbed it and struck down a thousand men.

In both cases these Judges, servants of God were faced with a task that in human thinking seemed impossible.  Yet they didn’t give in or give up, they used what they had:

1) Faith, trust in God, calling and power of God

2)  Shamgar also used what he had in the earthly sense an oxgoad while Samson used what he had, the jawbone of a donkey.

God has equipped us with what we need to achieve the victory. If only we use what we have.  Important is to remain confidant and see and use it.
