Acts 20:32 [I commend you to the word of grace…] to give you an inheritance among all them which are sanctified.
The second promise that comes to us from the word of grace is this: the Gospel gives you an inheritance among the saints. Among the many spiritual blessings we receive from the hearing of the gospel is an inheritance. The inheritance is the Kingdom of God, eternal life in the presence of God, a place in the new heaven and the new earth, a new name in the family of God, and the invisible Church made up of all the saints (believers in Christ). The spiritual and eternal inheritance is a fulfillment of the promise of “land” given to Abraham, Isaac, and Jacob.
An inheritance is not something that can be earned, deserved, or worked for. Inherited wealth is earned by someone else and granted as a gift to a person of the testator’s choosing, usually a family member whom he loves. In the case of God the Father, all we have to do is be born in the family. ”He has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead, to an inheritance…kept in heaven for you [1 Peter 1:3-4].”
Being born is not something we can take credit for: so also is being born again. God is the cause, and all we can do is rejoice in the gift of life, receive it with God-given faith, and thank Him for the promise every day. We are children of God and we have an inheritance kept in heaven and sealed in our hearts by the Spirit.
