Romans 8:12-17
It is our faith that must be exercised; we must work out our faith in fear and trembling, but all this is in, by, and through the indwelling power of the Holy Spirit.
But when the Bible talks about the fatherhood of God, it never does so in the sense of God’s creation. To address God as Father involves a relationship of intimacy. To be a member in good standing in the family of God is a privilege never to be passively assumed or taken for granted. In fact it is the greatest privilege of all, to be able to come to God and address him as Father. And we are not able to do that by nature, because by nature we are children of wrath
The brotherhood in biblical categories has to do with those who share the intimacy of fellowship with God, and with Christ who is the Son of God.
But the Bible doesn’t describe that in terms of brotherhood. Paul, in verse 12 for example, uses the term ‘brothers’ to refer to a special group, those who are in the brotherhood and sisterhood of faith because they have a unique relationship to Christ and are those in whom the Spirit of Christ dwells. Who are the children of God? They are those who are led by the Spirit of God.
In the NT the word occurs 3 times, transliterated into Greek; in each instance it is a vocative, addressed to God, and the Greek equivalent is appended (Mk. 14:36; Rom. 8:15; Gal. 4:6). It appears that the double phrase was common in the Greek-speaking church, where its use may well have been liturgical. (The Lord’s Prayer in its Aramaic form probably began with ’abba.)
It appears that it was Jesus who first applied the term to God, and who gave authority to his disciples to do so. Paul sees in its use a symbol of the Christian’s adoption as a son of God and his possession of the Spirit.
The work of the Spirit is not only to make us children of God, and then to take up a dwelling place within our hearts, but also to give us an inner assurance of our standing with God. It is vitally important for the Christian to have assurance of salvation for we are heirs—heirs of God and co-heirs with Christ, if indeed we share in his sufferings in order that we may also share in his glory.
To be an heir is to be rightfully in line to inherit what is in store for you. Because of our adoption into the family of God we are no longer strangers, nor are we of our original father, the devil. Instead, we possess an inalienable right to receive all that God has promised to give to each of his children, beginning with our elder Brother, Christ. What we know of this inheritance is largely symbolic, and much in Revelation speaks to the riches that will be bestowed upon us. Chief among them will not be things, but greater intimacy with Christ than we presently enjoy.
