The inheritance I speak of is the only inheritance which is within every body's reach. Most men can never obtain riches and greatness, though they labour hard for them all their lives. But glory, honour, and eternal life, are offered to every man freely, who is willing to accept them on God's terms. "Whosoever will," may be an "heir of God, and joint heir with Christ."
If any reader of this paper wishes to have a portion of this inheritance, let him know that he must be a member of that one family on earth to which it belongs, and that is the family of all true Christians. You must become one of God's children on earth, if you desire to have glory in heaven. I write this paper in order to persuade you to become a child of God this day, if you are not one already. I write it to persuade you to make sure work that you are one, if at present you have only a vague hope, and nothing more. None but true Christians are the children of God! None but the children of God are heirs of God! Give me your attention, while I try to unfold to you these things, and to show the lessons contained in the verses which head this page.
I. Let me show the relation of all true Christians to God. They are "sons of God."
II. Let me show the special evidences of this relation. True Christians are "led by the Spirit." They have "the Spirit of adoption." They have the "witness of the Spirit." They "suffer with Christ."
III. Let me show the privileges of this relation. True Christians are "heirs of God, and joint heirs with Christ."
I. First let me show the relation of all true Christians to God. They are God's "Sons."
I know no higher and more comfortable word that could have been chosen. To be servants of God,—to be subjects, soldiers, disciples, friends,—all these are excellent titles; but to be the "sons" of God is a step higher still. What says the Scripture? "The servant abideth not in the house for ever, but the Son abideth ever." (John viii. 35.)
To be son of the rich and noble in this world,—to be son of the princes and kings of the earth,—this is commonly reckoned a great temporal advantage and privilege. But to be a son of the King of kings, and Lord of lords,—to be a son of the High and Holy One, who inhabiteth eternity,—this is something far higher. And yet this is the portion of every true Christian.
The son of an earthly parent looks naturally to his father for affection, maintenance, provision, and education. There is a home always open to him. There is a love which, generally speaking, no bad conduct can completely extinguish. All these are things belonging even to the sonship of this world. Think then how great is the privilege of that poor sinner of mankind who can say of God, "He is my Father."
But how can sinful men like ourselves become sons of God? When do we enter into this glorious relationship? We are not the sons of God by nature. We were not born so when we came into the world. No man has a natural right to look to God as his Father. It is a vile heresy to say that he has. Men are said to be born poets and painters,—but men are never born sons of God. The Epistle to the Ephesians tells us, "Ye were by nature children of wrath, even as others." (Ephes. ii. 3.) The Epistle of St. John says, "The children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God." (1 John iii. 10.) The Catechism of the Church of England wisely follows the doctrine of the Bible, and teaches us to say, "By nature we are born in sin, and children of wrath." Yes: we are all rather children of the devil, than children of God! Sin is indeed hereditary, and runs in the family of Adam. Grace is anything but hereditary, and holy men have not, as a matter of course, holy sons. How then and when does this mighty change and translation come upon men? When and in what manner do sinners become the "sons and daughters of the Lord Almighty?" (2 Cor vi. 18.)
Men become sons of God in the day that the Spirit leads them to believe on Jesus Christ for salvation, and not before.[13] What says the Epistle to the Galatians? "Ye are all the children of God by faith in Christ Jesus." (Gal. iii. 26.) What says the first Epistle to the Corinthians? "Of Him are ye in Christ Jesus." (1 Cor. i. 30.) What says the Gospel of John? "As many as received Christ, to them gave He power (or privilege) to become the sons of God, even to them that believe on His name." (John i. 12.) Faith unites the sinner to the Son of God, and makes him one of His members. Faith makes him one of those in whom the Father sees no spot, and is well-pleased. Faith marries him to the beloved Son of God, and entitles him to be reckoned among the sons. Faith gives him "fellowship with the Father and the Son." (1 John i. 3.) Faith grafts him into the Father's family, and opens up to him a room in the Father's house. Faith gives him life instead of death, and makes him, instead of being a servant, a son. Show me a man that has this faith, and, whatever be his church or denomination, I say that he is a son of God.
This is one of those points we should never forget. You and I know nothing of a man's sonship until he believes. No doubt the sons of God are foreknown and chosen from all eternity, and predestinated to adoption. But, remember, it is not till they are called in due time, and believe,—it is not till then that you and I can be certain they are sons. It is not till they repent and believe, that the angels of God rejoice over them. The angels cannot read the book of God's election: they know not who are "His hidden ones" in the earth. (Ps. lxxxiii. 3.) They rejoice over no man till he believes. But when they see some poor sinner repenting and believing, then there is joy among them,—joy that one more brand is plucked from the burning, and one more son and heir born again to the Father in heaven. (Luke xv. 10.) But once more I say, you and I know nothing certain about a man's sonship to God until he believes on Christ.
