The Character and Privileges of the Children of God.

I. The distinguishing characteristic of the children of God.—1. It is a spirit of filial confidence as opposed to servile fear. No unpardoned sinner has a sufficient ground of confidence in God. Till assured that God loves him, he knows not how God may treat him at any particular time. But we cannot believe that God loves us and at the same time doubt His mercy. He that heartily reposes on God’s favour cannot dread His vengeance.

2. This filial spirit is one of holy love as opposed to the bondage of sin.—The love of God is a powerful element well calculated to change the whole of our inner man. It gives a new bias to our wayward affections and a healthful vigour to every good desire.

3. The filial spirit is one of ready obedience as opposed to the gloomy spirit of servitude.—The service of a slave is unwilling, extorted, unsatisfactory; the obedience of a child is ready, loving, energetic. Love is self-denying, soul-absorbing, devoted.

II. Some of the distinguishing privileges of the children of God.—1. The child of God has a part in the Father’s love and care. 2. Has a filial resemblance to the heavenly Father. 3. Children of God have the privileges of family communion and fellowship. 4. Have a share in the family provisions. 5. Have a title to the future inheritance.—Robert M. Macbrair.

Ver. 7. God’s Offspring.—1. This is the state of all poor heathen, whether in England or foreign countries: they are children, ignorant and unable to take care of themselves, because they do not know what they are. Paul tells them they are God’s offspring, though they know it not. He does not mean that we are not God’s children till we find out that we are God’s children. You were God’s heirs all along, although you differed nothing from slaves; for as long as you were in heathen ignorance and foolishness God had to treat you as His slaves, not as His children. They thought that God did not love them, that they must buy His favours. They thought religion meant a plan for making God love them. 2. Then appeared the love of God in Jesus Christ, who told men of their heavenly Father. He preached to them the good news of the kingdom of God, that God had not forgotten them, did not hate them, would freely forgive them all that was past; and why? Because He was their Father and loved them so that He spared not His only begotten Son. And now God looks at us in the light of Jesus Christ. He does not wish us to remain merely His child, under tutors and governors, forced to do what is right outwardly and whether it likes or not. God wishes each of us to become His son, His grown-up and reasonable son. 3. It is a fearful thing to despise the mercies of the living God, and when you are called to be His sons to fall back under the terrors of His law in slavish fear and a guilty conscience and remorse which cannot repent. He has told you to call Him your Father; and if you speak to Him in any other way, you insult Him and trample underfoot the riches of His grace. You are not God’s slaves, but His sons, heirs of God and joint-heirs of Christ. What an inheritance of glory and bliss that must be which the Lord Jesus Christ Himself is to inherit with us—an inheritance of all that is wise, loving, noble, holy, peaceful, all that can make us happy and like God Himself.—C. Kingsley.
