Redemption is the final work of God.  We have been redeemed to an extent, but the redemption that Christ purchased is not fully apparent.  If we have been saved from death to life, why do we die?  Everyone we know dies.

God's plan is that no one will ever die again.  God planned to end all death by sacrificing Himself on the cross.  His plan is that every person would be born again by the blood of Jesus.  Then, by grace, which is through faith, He planned that we would receive the gift of righteousness--not ours but God's within us.  Righteousness leads to holiness--not ours, but God's within us.  Holiness leads to the redemption of our spirits, minds, and bodies.  This is complete redemption.

We wait for the manifestation, the removal of the veil of the fleshly nature and the redemption of our bodies.  This will also be the beginning of the release of all of creation from bondage.  Romans 8:18-23We will all come into total unity of the faith and of the knowledge of the Son of God.  God will cause this to come about by righteousness and holiness, which He will complete in us.  The extent of our unity will go way beyond human unity, because we will be in unity with the Head, Christ Jesus, and the Body of Christ to the extent that we will be one totally complete man.  And this can be described as the measure of the stature of the fullness of Christ.  That is the coming of the Kingdom and it is the Manifestation of the Sons of God.  Ephesians 4:11-12.

This, of course, is the Perfect Day mentioned in Proverbs.  Proverbs 4:18

This is the great and terrible day of the Lord.  2 Peter 3:10-14, Amos 5:18, Isaiah 13:6

This is Jesus coming in His Body, which precedes His triumphant bodily return. 2 Peter 1:16
