Romans 8:31-39
Notice Paul uses a word in verse 32 that would be easy to miss if we read over it too quickly. It is the word idion—he that spared not his own Son. Why does Paul put in that qualifier? Why does he not just say, He that spared not his Son?
Well, in this chapter he has expounded the whole concept of adoption. But there is a distinction that the apostle makes here. God has an only-begotten Son who is uniquely the Son of God and that’s what the Greek means here when the apostle speaks of his own Son. His own Son is distinguished from all those who are sons of God by adoption.
Paul is saying this: Look at the extent to which God has gone to ensure our ultimate victory. He has spared nothing to bring it about, not even his own Son. Here Paul refers to the inheritance the Father has laid up for the Son being shared with us, and our participation in the benefits of what rightfully belongs to Christ alone. God delivers up his own Son for us, and in doing so he is willing to give us everything that he has promised and set apart for his Son.
Divine sovereignty is the ultimate source of comfort for the Christian believer, because it means that God is in control of his destiny. What could be more comforting to the Christian than to know that the outcome of his life is not in the hands of fortuitous circumstances, but is in the hands of a benevolent God?
Suppose the Spirit has convicted me of my sin, and I have confessed it. God has promised to forgive my sin, but Satan starts telling me, ‘How can you be a Christian? Look at what you did!’ As he starts taking away my peace, it is at that point I am to say, ‘Satan, who shall lay any charge to God’s elect? Get out of here! You have nothing to say because I am a justified man.’ It is God who justifies. That is the point the apostle is making here. God, the supreme Governor, the supreme Judge, has declared that I am justified.
Christ is our Advocate, as well as our Judge. Even now he is making intercession for us. So my sin has been covered from every conceivable angle.
