Therefore you have no excuse, O man, every one of you who judges. For in passing judgment on another you condemn yourself, because you, the judge, practice the very same things. 2 We know that the judgment of God rightly falls on those who practice such things. 3 Do you suppose, O man—you who judge those who practice such things and yet do them yourself—that you will escape the judgment of God? 4 Or do you presume on the riches of his kindness and forbearance and patience, not knowing that God’s kindness is meant to lead you to repentance? 5 But because of your hard and impenitent heart you are storing up wrath for yourself on the day of wrath when God’s righteous judgment will be revealed.
Those who reject Christ, who are hard hearted toward their own sin and have hearts that are impenitent, they are storing up wrath. Jesus said in his sermon on the mount that we are to store up our treasure in heaven, but for those who remain unsaved, they are storing up wrath like treasure but theirs is being stored up for them in hell.
There will be a day of judgment when God’s righteous judgment is revealed. This is what Revelation 19 says when Christ returns a second time. In his judgment God will cause sinners to experience the fullness of the wrath that was stored up for them because of their sins.
That being said, let us remember verse 4, of God’s kindness and patience so that many will be led to repentance. This is what happened to you. Everyone who has put their trust in Jesus Christ has been freed from the pending judgment because all the wrath we were storing up has been placed on Christ on the cross. He suffered for it all and now we are no longer under condemnation. For this we should greatly rejoice. Our hearts should be full of joy and thanksgiving for his kindness towards us. My prayer is that you will be in awe of your savior for his great mercy and grace in your life because of his kindness.
However, your praise should also be tempered in sorrow as you consider the destination of your neighbor. God’s kindness toward you should cause you to warn your neighbor of the coming judgment and tell him or her how they too can experience God’s kindness.
