According to Truth. Romans 2:2-4 Strangely, it is not uncommon for self-righteous people to pass their own judgment on other people based upon their own selves and opinions. It seems by nature that we are blind to our own sins and sinful conditions but can easily see the condition of others. The Holy Spirit brings conviction of sin, righteousness, and judgment and will not overlook what the self-righteous person thinks of himself. It may have been, as some say, that the Jews thought they would be exempt from the judgment of God because they were a chosen nation. They thought only Gentiles would be judged by a righteous God according to the truth. The fact is that God judges every person justly on the basis of undeniable facts. “We know” eternal rules of justice, fairness, and conduct are based on truth.
It is very important that we all, whether Jews or Gentiles, realize that the judgment of God is according to truth, not nationality, culture, or religious creed. Any person who thinks they are important and do not face their own sin as a repentant sinner will find themselves judged by a righteous God, just like all other men. Therefore, God is a God of truth and must judge according to truth. All the facts, the acts, and the motivation behind them are known to God. He who knows the "thoughts and intents" of every heart as well as the deeds needs no witnesses, jury, or opinions from men.
The one who judges others may think God will overlook his sins, but such an attitude and action are already condemned by God. Those who judge others do not seem to understand that God's goodness to them is to bring them to repentance themselves. How patient God is with us! He is longsuffering in view of giving the opportunity to repent, but not repenting of sin against the riches of God’s goodness has eternal consequences that are inescapable.
God's goodness preserves us, provides for us, and protects us. It withholds disease, danger, and even death from us. To despise that goodness endangers one who persists in following their own self-interests. God does not immediately unleash His wrath against sinners because of His goodness and forbearance. To despise God's goodness, forbearance, and long-suffering places the self-opinionated, ungrateful person under the wrath of God when His forbearance is finished. These things were all granted to us to bring us to repentance so that we might turn from being self-centered, judgmental people to humble, repentant sinners who gladly accept God's gracious salvation.
