And thinkest thou this, O man, that judgest them which do such things [list in Rom 1], and doest the same, that thou shalt escape the judgment of God? Or despisest thou the riches of His goodness and forbearance and longsuffering; not knowing that the Goodness of GOD leadeth thee to repentance? But after thy hardness and impenitent heart treasurest up unto thyself wrath against the Day of wrath and revelation of the righteous judgment of GOD; Who will render to every man according to his deeds:
For there is no respect of persons with GOD. (Romans 2:3-6,11)
Those that don't know Him, and have never been born again should fear that punishment. But after salvation; when we see, that is understand the Kingdom of GOD, we no longer serve Him out of fear but because we love Him who loved us and gave Himself for us.
I urge you if you are one who has never received Christ by faith do so today. GOD wants you to be in a right relationship with Him, and you cannot do it yourself. Repent and believe in Him for Salvation.
For the Christian, remember and review that you may show others of GOD's judgment and justice, but also His mercy and grace.
