Colossians 3:4

When Christ, Who is our life, appears, then you also will appear with Him in [the splendor of His] glory. Colossians 3:4

Christ, which is the power of God, is our life. We are not our life, Christ is our life. Christ is our power, our energy, our knowledge, our hope, our faith, our love, our forgiveness, our grace, our everything. We are now one with Him, all that He is, so are we. So why do we seek to call ourselves good? No one is good but God and we are now one with Him. We now, this very moment and every moment, have complete victory. 

Anyone who confesses (acknowledges, owns) that Jesus is the Son of God, God abides (lives, makes His home) in him and he [abides, lives, makes his home] in God. And we know (understand, recognize, are conscious of, by observation and by experience) and believe (adhere to and put faith in and rely on) the love God cherishes for us. God is love, and he who dwells and continues in love dwells and continues in God, and God dwells and continues in him. In this [union and communion with Him] love is brought to completion and attains perfection with us, that we may have confidence for the day of judgment [with assurance and boldness to face Him], because as He is, so are we in this world. There is no fear in love [dread does not exist], but full-grown (complete, perfect) love turns fear out of doors and expels every trace of terror! For fear brings with it the thought of punishment, and [so] he who is afraid has not reached the full maturity of love [is not yet grown into love's complete perfection]. 1 John 4:15-18

Our Father shows us that when Jesus appears that we too will appear with Him in glory. He also tells us that we will have boldness on the Day of Judgment. Ask yourself this, when does Jesus appear? Does He appear on Judgment Day or a thousand years before Judgment Day? The Bible tells us that Jesus appears a thousand years before Judgment Day when He ushers in the Millennial Reign of Christ. It is on this day that we will be changed, not on Judgment Day. 

And he gripped and overpowered the dragon, that old serpent [of primeval times], who is the devil and Satan, and [securely] bound him for a thousand years. Then he hurled him into the Abyss (the bottomless pit) and closed it and sealed it above him, so that he should no longer lead astray and deceive and seduce the nations until the thousand years were at an end. After that he must be liberated for a short time. Then I saw thrones, and sitting on them were those to whom authority to act as judges and to pass sentence was entrusted. Also I saw the souls of those who had been slain with axes [beheaded] for their witnessing to Jesus and [for preaching and testifying] for the Word of God, and who had refused to pay homage to the beast or his statue and had not accepted his mark or permitted it to be stamped on their foreheads or on their hands. And they lived again and ruled with Christ (the Messiah) a thousand years. The remainder of the dead were not restored to life again until the thousand years were completed. This is the first resurrection. Blessed (happy, [a]to be envied) and holy (spiritually whole, of unimpaired innocence and proved virtue) is the person who takes part (shares) in the first resurrection! Over them the second death exerts no power or authority, but they shall be ministers of God and of Christ (the Messiah), and they shall rule along with Him a thousand years. 20:2-6

Judgment Day holds no power over us, because we will be just like Jesus is on that day. We have passed from Judgment and we will judge along with Jesus. See how John tells us that He saw the Thrones, not the just the Throne. We will judge with Grace and Mercy with our Lord, Who we are one with on Judgment Day, we will not be judged.

I assure you, most solemnly I tell you, the person whose ears are open to My words [who listens to My message] and believes and trusts in and clings to and relies on Him Who sent Me has (possesses now) eternal life. And he does not come into judgment [does not incur sentence of judgment, will not come under condemnation], but he has already passed over out of death into life. John 5:24

Jesus is not going to be judged on Judgment Day and we are one with Him. We are going to rule with Him for a thousand years before Judgment Day and Jesus plainly tells us that we will not be judged. So don’t ever fret about Judgment Day.
