The chapter addresses those who are tempted to think they are good… those people who think, “I’m not as bad as some people, surely God would not condemn me!”
Paul comes out swinging in verse one. He says: You who judge become guilty of everything because of your judgement.
We see God's response to self-righteousness in verse five: “But because of your hard and impenitent heart you are storing up wrath for yourself on the day of wrath when God’s righteous judgement will be revealed.”
That is a punch to the face! He is saying: You are hardhearted, unwilling to repent of self-righteousness, so God's wrath is building up for you. And there will be a day when that wrath is poured out.
A lot of people, even in the church, don't believe in hell these days but scripture teaches that a day of judgement is coming that leads some to be cast away in to suffering. Revelation 20:11-15 paints a picture of that "day of wrath." It says that everyone will be judged based on what he has done. The good works of the redeemed and the sins of the impenitent. And those without Christ will face eternal suffering.
The bottom line in Romans 2:
You should examine your heart to see if you have truly submitted to the Gospel and surrendered your life to Jesus Christ. It is possible that some have come to agree generally that Christianity is right yet have not repented and surrendered to God's way. It is possible that some have reduced Christianity to behavior modification or morality improvement rather than surrendering to Jesus and entering personal relationship with God.
Friend, good is not good enough. Salvation involves a great exchanged. Christ gave his life, we give ours over to him and in that we get the greatest gift imaginable. We get God... now and forever.
as it is written: “None is righteous, no, not one; no one understands; no one seeks for God. All have turned aside; together they have become worthless; no one does good, not even one.”
