Question:  Are you living in God's power and is it possible to live in the supernatural strength and power of God? 

It is God's will for His people to live in His power and strength according to the scriptures.

Ephesians 1:18-19 The eyes of your understanding being enlightened; that you may know what is the hope of His calling, what are the riches of the glory of His inheritance in the saints, and what is the exceeding greatness of His power toward us who believe, according to the working of His mighty power.

Ephesians 3:20  Now to Him who is able to do exceedingly abundantly above all that we ask or think, according to the power that works in us.

Ephesians 6:10  Finally, my brethren, be strong in the Lord and in the power of His might.

2 Timothy 2:1  You therefore, my son, be strong in the grace that is in Christ Jesus.

The voice of an Angel to Joshua:

Joshua 1:9  Have I not commanded you? Be strong and of good courage; do not be afraid, nor be dismayed, for the Lord your God is with you wherever you go.

The scriptures prove that it is God's will for us to live in His power and strength and to be courageous.  Be resolute!

What about our weakness?

2 Corinthians 12:9-10  And He said to me, "My grace is sufficient for you, for My strength is made perfect in weakness." Therefore most gladly I will rather boast in my infirmities, that the power of Christ may rest upon me. Therefore I take pleasure in infirmities, in reproaches, in needs, in persecutions, in distresses, for Christ’s sake. For when I am weak, then I am strong.

When I recognize my weakness, then I can ask for and receive God's strength!

Hebrews 11:32-34  And what more shall I say? For the time would fail me to tell of Gideon and Barak and Samson and Jephthah, also of David and Samuel and the prophets: who through faith subdued kingdoms, worked righteousness, obtained promises, stopped the mouths of lions, quenched the violence of fire, escaped the edge of the sword, out of weakness were made strong, became valiant in battle, turned to flight the armies of the aliens.

Psalm 73:26  My flesh and my heart fail; but God is the strength of my heart and my portion forever.

God's will for us makes His power and strength possible, and it is our faith that makes it possible to live in God's power and strength.

Ephesians 1:19  What is the exceeding greatness of His power toward us who believe according to the working of His mighty power.

Have Courage

The angel said to Joshua, "Be strong and of good courage."  And the apostle Paul said, "Be brave.  Be strong."

When you trust in the Lord and live in His strength and power, you will become brave and courageous.  And fear will not abide in you.

2 Timothy 1:7  For God has not given us a spirit of fear, but of power and of love and of a sound mind.

Psalm 28:7  The Lord is my strength and my shield; my heart trusted in Him, and I am helped; therefore my heart greatly rejoices, and with my song I will praise Him.

The danger of being a coward and allowing unbelief is amplified in Revelation 21:8 "But the cowardly, unbelieving, abominable, murderers, sexually immoral, sorcerers, idolaters, and all liars shall have their part in the lake which burns with fire and brimstone, which is the second death."

What To Do

1.  Believe God's Word.  It is His will for you.
Proverbs 4:10  Hear, my son, and receive my sayings, and the years of your life will be many.

2.  Establish faith.
Romans 10:8  But what does it say?  "The word is near you, in your mouth and in your heart." 
That is the word of faith that we preach.

Verse 17 says:  So then faith comes by hearing and hearing by the word of God.

Meditate on the Word!

3.  Declare His will and Word.
Mark 11:22-24   So Jesus answered and said to them, "Have faith in God. For assuredly, I say to you, whoever says to this mountain, ‘Be removed and be cast into the sea,’ and does not doubt in his heart, but believes that those things he says will be done, he will have whatever he says. Therefore I say to you, whatever things you ask when you pray, believe that you receive them, and you will have them."

Job 22:28  You will also declare a thing, and it will be established for you; so light will shine on your ways.

David's Declaration
2 Samuel 22:29-33   "For You are my lamp, O LORD; The LORD shall enlighten my darkness. For by You I can run against a troop; By my God I can leap over a wall. As for God, His way is perfect; The word of the LORD is proven; He is a shield to all who trust in Him. For who is God, except the LORD? And who is a rock, except our God? God is my strength and power, And He makes my way perfect.

My Declaration
Ephesians 6:10  Be strong in the Lord and in the power of His might.

I am strong in spirit, soul and body!  I am strong in the Lord, and His strength is over my weakness.

Bottom Line
According to Romans 8:11, the Holy Spirit will quicken or give life to our mortal bodies. His spiritual power will invigorate us to increase our physical life and make us strong.
