Romans 2:4-5

Or do you have no regard for the wealth of His kindness and tolerance and patience [in withholding His wrath]? Are you [actually] unaware or ignorant [of the fact] that God’s kindness leads you to repentance [that is, to change your inner self, your old way of thinking—seek His purpose for your life]? But because of your callous stubbornness and unrepentant heart you are [deliberately] storing up wrath for yourself on the day of wrath when God’s righteous judgment will be revealed.
