Are you facing a hard time? Something that seems insurmountable? A mountain in your life? Get out your bible and read Zechariah 4:6-10. I will post the passage at the end if you don't have a bible. However, I strongly encourage you to use a bible.
I love this passage. When I read it, it literally spoke life into me. Just a little background first. The Israelites were in captivity and the temple of The Lord had been destroyed. The Lord told Zerubbable to rebuild the temple. However, they were still captive in the land that destroyed the temple. It seemed a bit impossible. Still, God had a plan. So, here are my thoughts on this particular passage.
First: He had to give his problem to God.
"Not by might not by power but by my spirit says The Lord or hosts." When we face difficult situations in our lives we have to stop using our human strength, no matter how amazing and wonderful and strong we are, and lean on the Spirit of God.
Second: When we lean on God amazing things happen.
"Who art thou, O great mountain? before Zerubbabel thou shalt become a plain." When we face the mountains in life with the Spirit of God they can become plains. It doesn't matter what that mountain is, God is still bigger, stronger, and more powerful, not to mention wise. He can level those mountains in an instant if you stop trying to do things in your human strength. But I would like to add that just because he can, doesn't mean he will right away. Sometimes we have to face things longer than we think we should. God is still there and he has a plan just trust him. Proverbs 3:5,6
Third: Even the smallest thing, if done in obedience, can make a huge difference.
"For who hath despised the day of small things? for they shall rejoice, and shall see the plummet in the hand of Zerubbabel..." When God asks you to do something do it, no matter how insignificant it seems. Zerubbable just had to take those first steps. What do you need to do? God expects us to do our part. We can't just sit back and say "Fix my life God!" and then not do anything. But when we do our part God will do amazing things through and for us. He doesn't leave us to do it all alone. So ask God "what do I need to do?" And then do it.
Zechariah 4:6-10 KJV
 Then he answered and spake unto me, saying, This is the word of the Lord unto Zerubbabel, saying, Not by might, nor by power, but by my spirit, saith the Lord of hosts.  Who art thou, O great mountain? before Zerubbabel thou shalt become a plain: and he shall bring forth the headstone thereof with shoutings, crying , Grace, grace unto it.  Moreover the word of the Lord came unto me, saying,  The hands of Zerubbabel have laid the foundation of this house; his hands shall also finish it; and thou shalt know that the Lord of hosts hath sent me unto you.  For who hath despised the day of small things? for they shall rejoice, and shall see the plummet in the hand of Zerubbabel with those seven; they are the eyes of the Lord , which run to and fro through the whole earth.
Proverbs 3:5-6 KJV
 Trust in the Lord with all thine heart; and lean not unto thine own understanding.  In all thy ways acknowledge him, and he shall direct thy paths.
