After we died to our old selves in baptism, after we live a life, like Jesus Christ, because our sins are forgiven and after we become like the sinless Jesus Christ doing good as well.

When people act like Jesus, they give example and point others to repentance, to God and salvation. What else must they do?

1Pet. 3:15 but sanctify Christ as Lord in your hearts, always being ready to make a defense to everyone who asks you to give an account for the hope that is in you, yet with gentleness and reverence;

What Do We Say?

1Pet. 2:22 WHO COMMITTED NO SIN, NOR WAS ANY DECEIT FOUND IN HIS MOUTH;
1Pet. 2:23 and while being reviled, He did not revile in return; while suffering, He uttered no threats, but kept entrusting Himself to Him who judges righteously;
1Pet. 2:24 and He Himself bore our sins in His body on the cross, so that we might die to sin and live to righteousness; for by His wounds you were healed.

1Pet. 1:17 ¶ If you address as Father the One who impartially judges according to each one's work, conduct yourselves in fear during the time of your stay on earth;
1Pet. 1:18 knowing that you were not redeemed with perishable things like silver or gold from your futile way of life inherited from your forefathers,
1Pet. 1:19 but with precious blood, as of a lamb unblemished and spotless, the blood of Christ.

Heb. 9:14 how much more will the blood of Christ, who through the eternal Spirit offered Himself without blemish to God, cleanse your conscience from dead works to serve the living God?

Heb. 4:15 For we do not have a high priest who cannot sympathize with our weaknesses, but One who has been tempted in all things as we are, yet without sin.

Rom. 6:3 Or do you not know that all of us who have been baptized into Christ Jesus have been baptized into His death?
Rom. 6:4 Therefore we have been buried with Him through baptism into death, so that as Christ was raised from the dead through the glory of the Father, so we too might walk in newness of life.
Rom. 6:5 For if we have become united with Him in the likeness of His death, certainly we shall also be in the likeness of His resurrection,
Rom. 6:6 knowing this, that our old self was crucified with Him, in order that our body of sin might be done away with, so that we would no longer be slaves to sin;
Rom. 6:7 for he who has died is freed from sin.
Rom. 6:8 ¶ Now if we have died with Christ, we believe that we shall also live with Him,
Rom. 6:9 knowing that Christ, having been raised from the dead, is never to die again; death no longer is master over Him.
Rom. 6:10 For the death that He died, He died to sin once for all; but the life that He lives, He lives to God.
Rom. 6:11 Even so consider yourselves to be dead to sin, but alive to God in Christ Jesus.

1Pet. 3:15 but sanctify Christ as Lord in your hearts, always being ready to make a defense to everyone who asks you to give an account for the hope that is in you, yet with gentleness and reverence;

Die as all humans but not for sins previously forgiven.
