Knowing God by J. I. Packer
“Sons of God” (Chapter 19)
What is a Christian?
“Sonship to God is not, therefore, a universal status into which everyone enters by natural birth, but a supernatural gift which one receives through receiving Jesus.” - J. I. Packer
John 1:12–13 NIV
12 Yet to all who did receive him, to those who believed in his name, he gave the right to become children of God—13 children born not of natural descent, nor of human decision or a husband’s will, but born of God.
Ephesians 1:5 NIV
5 he predestined us for adoption to sonship through Jesus Christ, in accordance with his pleasure and will—
The revelation to the believer that God is his Father is in a sense the climax of the Bible.
A New Relationship
“To those who are Christ’s, the holy God is a loving Father; they belong to his family; they may approach him without fear and always be sure of his fatherly concern and care. This is the heart of the New Testament message.” - J. I. Packer
God’s fatherly relation to Jesus in John’s Gospel:
John 6:38 NIV
38 For I have come down from heaven not to do my will but to do the will of him who sent me.
John 5:20 NIV
20 For the Father loves the Son and shows him all he does. Yes, and he will show him even greater works than these, so that you will be amazed.
John 8:29 NIV
29 The one who sent me is with me; he has not left me alone, for I always do what pleases him.”
John 17:1 NIV
1 After Jesus said this, he looked toward heaven and prayed: “Father, the hour has come. Glorify your Son, that your Son may glorify you.
John 5:22–23 NIV
22 Moreover, the Father judges no one, but has entrusted all judgment to the Son, 23 that all may honor the Son just as they honor the Father. Whoever does not honor the Son does not honor the Father, who sent him.
Each of these dimensions of fatherhood apply to us as believers as well:
John 12:26 NIV
26 Whoever serves me must follow me; and where I am, my servant also will be. My Father will honor the one who serves me.
Adoption: The Highest Privilege
A Formal Definition:
“All those that are justified, God vouchsafeth, in and for His only Son Jesus Christ, to make partakers of the grace of adoption: by which they are taken into the number, and enjoy the liberties and privileges of the children of God; have His name put upon them, receive the Spirit of adoption; have access to the throne of grace with boldness; are enabled to cry, Abba, Father; are pitied, protected, provided for, and chastened by Him, as by a father; yet never cast off, but sealed to the day of redemption, and inherit the promises, as heirs of everlasting salvation.” WCF 12
Adoption is the highest privilege that the gospel offers, higher even than justification.
According to the Scriptures, pardon, acceptance, and adoption, are distinct privileges, the one rising above the other in the order in which they have been stated . . . while the first two properly belong to (the sinner’s) justification, as being both founded on the same relation—that of a Ruler and Subject—the third is radically distinct from them, as being founded on a nearer, more tender, and more endearing relation—that between a Father and his Son. . . . There is a manifest difference between the position of a servant and a friend—and also between that of a servant and a son. . . . A closer and dearer intimacy than that of a master and servant is said to subsist between Christ and His people: “Henceforth I call you not servants: for the servant knoweth not what his lord doeth: but I have called you friends” (John 15:15); and a still closer and dearer relation is said to exist in consequence of adoption; for “Thou art no more a servant, but a son, and an heir of God through Christ” (Galatians 4:7). The privilege of adoption presupposes pardon and acceptance, but is higher than either; for, “To as many as received Him, to them gave he power”—not inward strength, but authority, right, or privilege—“to become the sons of God, even to them that believe on his name” (John 1:12). This is a higher privilege than of Justification, as being founded on a closer and more endearing relation—“Behold! what manner of love the Father hath bestowed on us, that we should be called the sons of God.” - James Buchanan, The Doctrine of Justification
Galatians 4:4–7 NIV
4 But when the set time had fully come, God sent his Son, born of a woman, born under the law, 5 to redeem those under the law, that we might receive adoption to sonship. 6 Because you are his sons, God sent the Spirit of his Son into our hearts, the Spirit who calls out, “Abba, Father.” 7 So you are no longer a slave, but God’s child; and since you are his child, God has made you also an heir.
Adoption: The Basis for Our Life
John 20:17–18 NIV
17 Jesus said, “Do not hold on to me, for I have not yet ascended to the Father. Go instead to my brothers and tell them, ‘I am ascending to my Father and your Father, to my God and your God.’” 18 Mary Magdalene went to the disciples with the news: “I have seen the Lord!” And she told them that he had said these things to her.
Christian Conduct
“...the sermon teaches Christian conduct not by giving a full scheme of rules and a detailed casuistry, to be followed with mechanical precision, but by indicating in a broad and general way the spirit, direction and objectives, the guiding principles and ideals, by which the Christian must steer his course…precisely the kind of moral instruction that parents are constantly trying to give their children.” - J. I. Packer
Three Principles of Christian Family Conduct:
Matthew 5:44–45 NIV
44 But I tell you, love your enemies and pray for those who persecute you, 45 that you may be children of your Father in heaven. He causes his sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous.
Matthew 5:48 NIV
48 Be perfect, therefore, as your heavenly Father is perfect.
Matthew 5:16 NIV
16 In the same way, let your light shine before others, that they may see your good deeds and glorify your Father in heaven.
Matthew 6:1 NIV
1 “Be careful not to practice your righteousness in front of others to be seen by them. If you do, you will have no reward from your Father in heaven.
Matthew 6:4 NIV
4 so that your giving may be in secret. Then your Father, who sees what is done in secret, will reward you.
Christian Prayer
Matthew 6:9 NIV
9 “This, then, is how you should pray: “ ‘Our Father in heaven, hallowed be your name,
“Jesus could say to his Father, “You always hear me” (Jn 11:42), and he wants his disciples to know that, as God’s adopted children, the same is true of them. The Father is always accessible to his children and is never too preoccupied to listen to what they have to say. This is the basis of Christian prayer.” - J. I. Packer
Matthew 6:7–8 NIV
7 And when you pray, do not keep on babbling like pagans, for they think they will be heard because of their many words. 8 Do not be like them, for your Father knows what you need before you ask him.
Matthew 7:7–11 NIV
7 “Ask and it will be given to you; seek and you will find; knock and the door will be opened to you. 8 For everyone who asks receives; the one who seeks finds; and to the one who knocks, the door will be opened. 9 “Which of you, if your son asks for bread, will give him a stone? 10 Or if he asks for a fish, will give him a snake? 11 If you, then, though you are evil, know how to give good gifts to your children, how much more will your Father in heaven give good gifts to those who ask him!
The Life of Faith
Matthew 6:25–26 NIV
25 “Therefore I tell you, do not worry about your life, what you will eat or drink; or about your body, what you will wear. Is not life more than food, and the body more than clothes? 26 Look at the birds of the air; they do not sow or reap or store away in barns, and yet your heavenly Father feeds them. Are you not much more valuable than they?
Matthew 6:31–33 NIV
31 So do not worry, saying, ‘What shall we eat?’ or ‘What shall we drink?’ or ‘What shall we wear?’ 32 For the pagans run after all these things, and your heavenly Father knows that you need them. 33 But seek first his kingdom and his righteousness, and all these things will be given to you as well.
