Those of us who accept Jesus Christ as our Lord and Savior understand that because Christ rose again, FIRST RESURRECTION, after He was crucified, we, too are "BLESSED" to partake in the eternal life it brings. However, HOLY is the key word in this phrase.

It is clear that as we enter the 1,000 year period, we are declared and perceived by God to be HOLY. It wasn't always that way. But at this point, we see the eternal state of believers, HOLY, confirmed (Romans 6:1-4-11). Amazingly, this eternal state for each of us is/was known before the earth even was created (Ephesians 1:3-4-14).

The BLESSED and HOLY ones will NEVER see the SECOND DEATH (the LAKE OF FIRE, verse 14). In fact, what we see here is the contrasting eternal state of the unbeliever or wicked. This is when the "wages" will be paid forever (Romans 6:15-23).
