That Settles Ownership - or does it?   

And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together. - Rom 8:17 Joint Heirs means that we share in all things - the Glory and the Persecution.

Wherefore you are no more a servant, but a son; and if a son, then an heir of God through Christ. - Gal 4:7 We went from Servants of the Law to Sonship and so Heirs of God.

Let me See, the Earth is the Lord's.   But He made us His Heirs.   Then our Lord Died, so His Will went into effect.   It Follows that we should Inherit what belonged to Him.   

Now, before anyone gets excited let me state clearly that this Inheritance is effective only when we are in Christ.   

So, technically, God's estate stays intact even though His Will ( Covenant) is testated.   

The point being made here is that the Earth belongs to God's Children.   

What does this mean?   

First of All we are commanded what to do:

And he said unto them, Go you into all the world, and preach the gospel to every creature. - Mar 16:15 This is the Great Commission.     It is still in force.     We are expected to carry the Gospel to every creature.      Jesus did not expect every person to believe, but He wants us to make sure all nations hear the Gospel as it is a criteria for His return.     Mat 24:14

The Purpose of this Command was for us to make non-believers into Believers, i.e.   Children of God.   

There is no land-grab implied by our Ownership of Earth.   We are to Focus on the Gospel of Christ Jesus.   

Jesus told us:

But seek you first the kingdom of God, and his righteousness; and all these things shall be added unto you. - Mat 6:33 Understanding and adopting this Spiritual Law is the secret to Abundant Life.      So, how do we seek righteousness?      We believe the Gospel and receive the righteousness of the Lord Jesus Christ by faith in Him.      The kingdom of God is the kingdom of Jesus Christ in whom rests all power in heaven and earth.

Hence, by focusing on the Gospel we defacto Receive the material aspects of our Inheritance.   

This happens, though, as we attack every Stronghold of the Enemy.   

For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places. - Eph 6:12 Flesh and Blood is needed to impact the people of Earth in the Physical Realm.     That is why God made Himself a Body and we called Him Jesus whose purpose was to Redeem us from our Lost state.     Likewise, Satan uses Flesh and Blood people to do his work in the Earth.      Spiritual Wickedness is the foundation for the attacks against our Faith and our Work for the Kingdom Of God.     That Spiritual Wickedness comes from Satan through His Deception of mankind.     Darkness is where Satan rules, using his powers of persuasion to convince men to turn away from God.     When a person rejects Christ they become a Child Of Satan and unknowlingly or willingly become his instrument to Steal, Kill and Destroy.

So, we must spread the Gospel in High Places in Order take Ownership.   

Any non-believer who is in a position of Authority on Earth is a squatter, a pretender.   

And I say also unto you, That you are Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it. - Mat 16:18 The Rock is 'the Testimony of Jesus Christ'.     It is what Saves us and enables us to Overcome.     Rev 12:11 The Church is the Body of all Believers in Christ Jesus.     The Body is made up of people with 'the Testimony of Jesus Christ'.      The Gates Of Hell will not withstand the Church when the Church wields its Testimony.

We are to unseat the Enemy by converting his followers into Believers.   

Let's get to Work !   

Don't be Afraid of the giants.   

We are well able to take the land!   

Though we are Heirs the Ownership of ourselves is clearly God.   He owns us:

By Creation :

The earth is the LORD's, and the fulness thereof; the world, and they that dwell therein. - Psm 24:1 Everything belongs to God and He gives it to whom He Will.

By Redemption :

For you are bought with a price: therefore glorify God in your body, and in your spirit, which are God's. - 1Co 6:20 We belong to Him, bought by His own life.     Rom 12:1

By Infilling :

What?     know you not that your body is the temple of the Holy Spirit which is in you, which you have of God, and you are not your own? - 1Co 6:19 Your body is the vehicle for your soul.      Since you are a New Spirit being In Christ, the challenge is to invert the order of dominance in your life.      Rather than being motivated by the flesh first, emotions second and spirit third, you should be motivated by the New Spirit which directs your soul which controls your body.      The Holy Spirit and your New Spirit are one.      By following the new order of spirit, soul then body, the Holy Spirit is able to direct your life, using your body as His vehicle just as He did our Lord Jesus Christ.      For this new order to be effected, your mind (soul) must be transformed to the Mind Of Christ.
