What does the Bible say about being blessed and holy?

In Revelation 20:6, the scripture declares, 'Blessed and holy is he that hath part in the first resurrection.' This blessing is not just a superficial happiness but denotes a deep spiritual favor bestowed by God. In this context, being 'blessed' refers to a state of spiritual well-being that transcends earthly circumstances, and being 'holy' implies a separation unto God, signifying that those partaking in this resurrection are set apart for His divine purposes. This is echoed in Ephesians 1:4, where we see that believers are chosen to be holy and blameless before God, reinforcing the notion that holiness is a gift from God, not something we can achieve on our own.
