Jesus Christ, as the Son of God, and as the victor in the spiritual
conflict, is the heir of all things. Heb. 1:1-4
Inheritance is based on sonship:
John 1:12, But as many as received Him, to them He gave the right to become children of God, even to those who believe in His name,
Rom. 8:16,17, The Spirit Himself bears witness with our spirit that we are children of God, and if children, heirs also, heirs of God and fellow heirs with Christ, if indeed we suffer with Him in order that we may also be glorified with Him.
Gal. 3:26-29, For you are all sons of God through faith in Christ Jesus. For all of you who were baptized into Christ have clothed yourselves with Christ. There is neither Jew nor Greek, there is neither slave nor free man, there is neither male nor female; for you are all one in Christ Jesus. And if you belong to Christ, then you are Abraham's offspring, heirs according to promise.
To inherit from God, a person must possess the life of God, that is, salvation resulting in eternal life.
Titus 3:5-7, He saved us, not on the basis of deeds which we have done in righteousness, but according to His mercy, by the washing of regeneration and renewing by the Holy Spirit, whom He poured out upon us richly through Jesus Christ our Savior, that being justified by His grace we might be made heirs according to the hope of eternal life.
1 John 5:11, 12 And the witness is this, that God has given us eternal life, and this life is in His Son. He who has the Son has the life; he who does not have the Son of God does not have the life.
Therefore, salvation is the qualification for inheriting from God.
Col. 1:9-14
We have an inheritance because we share the destiny of Christ. The true doctrine of predestination is that we share Christ's destiny.
Eph. 1:11, also we have obtained an inheritance, having been predestined according to His purpose who works all things after the counsel of His will,
As joint-heirs with Christ, we also share Christ's election.
Heb. 9:15, And for this reason He is the mediator of a new covenant, in order that since a death has taken place for the redemption of the transgressions that were committed under the first covenant, those who have been called may receive the promise of the eternal inheritance.
Our heritage is related to the doctrine of Eternal Security.
1 Pet. 1:3-5, Blessed be the God and Father of our Lord Jesus Christ, who according to His great mercy has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead, to obtain an inheritance which is imperishable and undefiled and will not fade away, reserved in heaven for you, who are protected by the power of God through faith for a salvation ready to be revealed in the last time.
The indwelling of the Holy Spirit is the down payment on our inheritance.
Eph. 1:14
Abraham's inheritance is the pattern and illustration of the heritage
of believers.
Rom. 4:9-16
