Judges 7:2 (TNIV)
'The Lord said to Gideon "you have too many men. I cannot deliver Midian into their hands, or Israel would boast against me 'my own strength has saved me."'
God knows us so intricately. He has such an innate understanding of human weakness that he is able to predict our pride. God can see when it will flare up, and sabotage our walk with Him - so, He works out our circumstances to protect us from it.
(Zechariah 4:6+10)
"Not by might nor by power, but by my spirit." says the Lord...
Who dares despise the days of small things...?"
The Word tells us that God's style is to use small beginnings and despised things to point towards His glory, and to keep us close to His heart, because we are unable to do anything alone.
We are not given the full picture of how He will cause His Kingdom to come to earth, we are only given the enormous honour of participating in the process.
Examine the things you are trying to do; if you had all the answers, resources and skills to accomplish them from the outset, rather than finding them in the journey according to His plan, how would pride affect you?
