Never Put Your Trust In Man!

Although God may use man/woman to bless you, as much as you should show your gratitude to them, that does not mean you should put your trust in man.  See he or she was just an instrument.  If they didn't do it for you, God would use another person to bless you because He cares for you deeply.
Likewise, do not put your trust in your own ability as man. Your human strength will fail you. For it is not my power, nor by might, but by my Spirit says the Lord. 

Never put your trust in man. JEREMIAH 17:5-8 CEV, "I, the [Lord], have put a curse on those who turn from me and trust in human strength.  They will dry up like a bush in salty desert soil, where nothing can grow.

But I will bless those who trust me, the [Lord].   They will be like trees growing beside a stream— trees with roots that reach down to the water, and with leaves that are always green.  They bear fruit every year and are never worried by a lack of rain."

Yes, be prepared always. Get educated, be informed, become skillful etc. But always remember, that without God, you will achieve nothing.  Ecclesiastes 9:11 NLT..."I have observed something else under the sun. The fastest runner doesn't always win the race, and the strongest warrior doesn't always win the battle. The wise sometimes go hungry, and the skillful are not necessarily wealthy. And those who are educated don't always lead successful lives. It is all decided by chance, by being in the right place at the right time."
