Romans 2:16
on that day when, according to my gospel, God judges the secrets of men by Christ Jesus.
There will come a day when God judges mankind. Many people deny it but all will be subject to God’s judgment.
Some say that the Gospel is all about acceptance and tolerance. They don’t want to see God as a judge or their actions as subject to judgment by His divine standard. Paul’s gospel message is not like this. Judgment is as much a part of the gospel as is grace, mercy and forgiveness. It is because of judgment that the gospel of Jesus is even needed. If our sin is not going to be judged then Jesus suffer and died for nothing.
God will judge people’s secret sins as well as their public ones. Even people who seem to be moral and above reproach will be judged by their thoughts, desires and motives.
God will judge by Jesus. Those who believe in His death, burial and resurrection as payment for their sins will be judged as right before God and will spend eternity with Him. All others will be judged as the sinners they are and will spend eternity in hell.
