Thank God for your weakness.

Thank God for your poverty.

Thank God for your illness.

Thank God for your homelessness.

Thank God for your depression.

Thank God for your loneliness.

You could be the demon-slayer God is looking for.

Psalm 18:17,34,40-41
   He delivered me from my strong enemy, and from them which hated me: for they were too strong for me.
   …He teacheth my hands to war, so that a bow of steel is broken by mine arms.
   …Thou hast also given me the necks of mine enemies; that I might destroy them that hate me.
   They cried, but there was none to save them: even unto the LORD, but he answered them not.

Moses lived to the age of 120 years.

When he was young and mighty, he was ready and willing to free his Israelites from Egyptian oppression.

It did not go well.

Acts 7:22-25,29
   And Moses was learned in all the wisdom of the Egyptians, and was mighty in words and in deeds.
   And when he was full forty years old, it came into his heart to visit his brethren the children of Israel.
   And seeing one of them suffer wrong, he defended him, and avenged him that was oppressed, and smote the Egyptian:
   For he supposed his brethren would have understood how that God by his hand would deliver them: but they understood not.
   …Then fled Moses at this saying, and was a stranger in the land of Madian, where he begat two sons.

The once mighty Moses was now a shepherd for his father in law…
Exodus 3:1
   Now Moses kept the flock of Jethro his father in law, the priest of Midian: and he led the flock to the backside of the desert, and came to the mountain of God, even to Horeb.

…for 40 years.
Acts 7:30
   And when forty years were expired…

After 40 years, God approached the 80 year old Moses.

Instead of jumping at the chance lead the Israelites, a broken Moses said to God: Couldn’t you just get someone else?
Exodus 3:11
   And Moses said unto God, Who am I, that I should go unto Pharaoh, and that I should bring forth the children of Israel out of Egypt?

Exodus 4:10
   And Moses said unto the LORD, O my Lord, I am not eloquent, neither heretofore, nor since thou hast spoken unto thy servant: but I am slow of speech, and of a slow tongue.

Jeremiah also did not believe that he could do God's work.
In his case, Jeremiah felt that he was too young.
Jeremiah 1:6-7
   Then said I, Ah, Lord GOD!  behold, I cannot speak: for I am a child.
   But the LORD said unto me, Say not, I am a child: for thou shalt go to all that I shall send thee, and whatsoever I command thee thou shalt speak.

God doesn’t use those who are too strong (handling life's problems with their own 'good' works).

1 Corinthians 1:27
   God hath chosen the weak things of the world to confound the things which are mighty;

The weak cast down the synagogue of Satan.
Revelation 3:8-9
   I know thy works: behold, I have set before thee an open door, and no man can shut it: for thou hast a little strength, and hast kept my word, and hast not denied my name.
   Behold, I will make them of the synagogue of Satan, which say they are Jews, and are not, but do lie; behold, I will make them to come and worship before thy feet, and to know that I have loved thee.

Why does God choose the weak to fight for victory?

So that the glory of the victory can be where it belongs – entirely for God.

God had Gideon reduce his army from 32,000 to 300, so that the glory would be for God alone.
Judges 7:2
   And the LORD said unto Gideon, The people that are with thee are too many for me to give the Midianites into their hands, lest Israel vaunt themselves against me, saying, Mine own hand hath saved me.

Zechariah 12:8
   In that day shall the LORD defend the inhabitants of Jerusalem; and he that is feeble among them at that day shall be as David; and the house of David shall be as God, as the angel of the LORD before them.

Leviticus 26:8
   And five of you shall chase an hundred, and an hundred of you shall put ten thousand to flight: and your enemies shall fall before you by the sword.

Deuteronomy 32:30
   How should one chase a thousand, and two put ten thousand to flight, except their Rock had sold them, and the LORD had shut them up?

Isaiah 40:29-31
   He giveth power to the faint; and to them that have no might he increaseth strength.
   Even the youths shall faint and be weary, and the young men shall utterly fall:
   But they that wait upon the LORD shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint.

The Lord delivers his broken and contrite people from enemies.

Psalm 34:18-19
   The LORD is nigh unto them that are of a broken heart; and saveth such as be of a contrite spirit.
   Many are the afflictions of the righteous: but the LORD delivereth him out of them all.

Psalm 51:17
   The sacrifices of God are a broken spirit: a broken and a contrite heart, O God, thou wilt not despise.

How does God give this victory to his weak people?

Via grace.

Grace is defined as the unmerited favor of God towards mankind.
We didn’t earn it or deserve it.
He gave it to us – for forgiveness of sins, but also for strength.
His strength in us.

2 Corinthians 12:9-10
   And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness.  Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me.
    Therefore I take pleasure in infirmities, in reproaches, in necessities, in persecutions, in distresses for Christ's sake: for when I am weak, then am I strong.

1 Corinthians 15:10
   But by the grace of God I am what I am: and his grace which was bestowed upon me was not in vain; but I laboured more abundantly than they all: yet not I, but the grace of God which was with me.    

2 Timothy 2:1,3
   Thou therefore, my son, be strong in the grace that is in Christ Jesus.
   …Thou therefore endure hardness, as a good soldier of Jesus Christ.

James 4:6
   But he giveth more grace.  Wherefore he saith, God resisteth the proud, but giveth grace unto the humble.

Now, on to the weapons.
