‘But unto them that are contentious’, that is, contentious against the truth, contentious against the law written on their hearts, those who shout these things down, those who discredit these things, and resist them, and make excuses. ‘To them that are contentious’, which implies there is a fight, even in the heart of the wicked to explain himself, to excuse himself.
Without God you are an obedient servant of temptation and evil, of unrighteousness, wrong thoughts, tempers, pride, and all the sins that have already been listed by Paul in chapter 1. You obey them. If you're not a believer in the Lord and you haven't found Christ and you don't belong to him. You may think you are free, but you're not. You're a hopeless, obedient servant of sin and unbelief. Everything the world tells you which builds up your unbelief, you latch onto it and obey it. Like a soldier, you stand to attention. To such people will come God's indignation and wrath, tribulation, pain and anguish. Oh, what bitter, bitter, tearful regret forever ‘upon every soul of man’, every individual, ‘that doeth evil’, whether he's a Jew or whether he's a Gentile; it doesn't matter.
What an amazing thing when we stand in judgment we are going to be rewarded for what we received by grace. We are going to be rewarded for what Christ and the Spirit of God have really done for us and in us. We are going to be rewarded for what was our delight and happiness. We shall be rewarded for what we were helped to do. That is the amazing privilege of the child of God in the Day of Judgment.
