Blessed are those: In response to the link between actions and final outcomes (Revelation 22:12), the seventh blessing of Revelation (see also 1:3; 14:13; 16:15; 19:9; 20:6; 22:7) promises acceptance for those who wash their robes. These are people purified by trusting in Christ and following him faithfully (Revelation 3:5; 6:11; 7:9–10, 14; 19:13; Ephesians 5:26; Hebrews 10:22).
