yea, I have a goodly heritage.
God, the Father had promised to give Jesus the nations for his inheritance, and 'the uttermost parts of the earth' for his possession (Psalm 2:8). Christ will be king over the entire earth.
Hebrews 1:2 says God "hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things."
But that's not all. He has also promised that we will share in His great inheritance! "Wherefore thou art no more a servant, but a son; and if a son, then an heir of God through Christ" (Galatians 4:7).
Romans 8:14-16 says, "As many as are led by the Spirit of God, they are the sons of God. For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father. The Spirit himself beareth witness with our spirit, that we are the children of God."
This isn't just some pie-in-the-sky talk. This is as real as it gets. Adoption speaks of love, mercy and grace. It is a legal action whereby a person is brought into a family in which he has no blood relationship. Adoption provides all the legal privileges that the other family members possess. Even though we were unworthy sinners God has chosen to legally adopt us; due to the blood Christ shed on the cross, we are now in the position of being a joint-heir with Jesus Christ.
The Holy Spirit also confirms our adoption in our spirits, which assures us that we are children of God. He did that by placing us into the family of God through the miracle of regeneration. He transferred us into God's family and confirms that reality in our hearts. We become legally and eternally children of God.
He has, by His legal right through His sovereignty, chosen us to bear His name and inherit His estate.
How do we know? If we are fruitful (2nd Peter 1) and obedient (1st John 3), we will receive the assurance from the Holy Spirit in our own spirits. Many people claim to be Christians when it isn't true; they have no confirmation of the Holy Spirit in their hearts. To those Jesus will say, "...depart from me; I never knew you."
Be certain that Jesus Christ is truly Lord of your life. He died for you while you were still a sinner with no hope. He wants to be your friend, your brother ... and you will bear His name and inherit eternal life.
