Who is there among the readers of this paper that _is a son of God indeed_? Rejoice, I say, and be exceeding glad of your privileges. Rejoice, for you have good cause to be thankful. Remember the words of the beloved apostle: "Behold what manner of love the Father hath bestowed upon us, that we should be called the sons of God." (1 John iii. 1.) How wonderful that heaven should look down on earth,--that the holy God should set His affections on sinful man, and admit him into His family! What though the world does not understand you! What though the men of this world laugh at you, and cast out your name as evil! Let them laugh if they will. God is your Father. You have no need to be ashamed. The Queen can create a nobleman. The Bishops can ordain clergymen. But Queen, Lords, and Commons,--bishops, priests, and deacons,--all together cannot, of their own power, make one son of God, or one of greater dignity than a son of God. The man that can call God his Father, and Christ his elder brother,--that man may be poor and lowly, yet he never need be ashamed. II. Let me show, in the second place, _the special evidences of the true Christians relation to God_. How shall a man make sure work of his own sonship? How shall he find out whether he is one that has come to Christ by faith and been born again? What are the marks and signs, and tokens, by which the "sons of God" may be known? This is a question which all who love eternal life ought to ask. This is a question to which the verses of Scripture I am asking you to consider, like many others, supply an answer. (1) The sons of God, for one thing, are all _led by His Spirit_. What says the Scripture which heads this paper? "As many as are led by the Spirit of God, they are the sons of God." (Rom. viii. 14.) They are all under the leading and teaching of a power which is Almighty, though unseen,--even the power of the Holy Ghost. They no longer turn every man to his own way, and walk every man in the light of His own eyes, and follow every man his own natural heart's desire. The Spirit leads them. The Spirit guides them. There is a movement in their hearts, lives, and affections, which they feel, though they may not be able to explain, and a movement which is always more or less in the same direction. They are led away from sin,--away from self-righteousness,--away from the world. This is the road by which the Spirit leads God's children. Those whom God adopts He teaches and trains. He shows them their own hearts. He makes them weary of their own ways. He makes them long for inward peace. They are led to Christ. They are led to the Bible. They are led to prayer. They are led to holiness. This is the beaten path along which the Spirit makes them to travel. Those whom God adopts He always sanctifies. He makes sin very bitter to them. He makes holiness very sweet.
