“Blessed are they that do his commandments, that they may have right to the tree of life, and may enter in through the gates into the city.”
King James Version (KJV)
22:14 Happy are they that do his commandments - His, who saith, I come - He speaks of himself. That they may have right - Through his gracious covenant. To the tree of life - To all the blessings signified by it. When Adam broke his commandment, he was driven from the tree of life. They who keep his commandments shall eat thereof.
Re 22:14 Blessed [are] they that do his commandments. "Blessed are they that wash their robes" (Revised Version). Those who have their robes washed are those whose sins are forgiven, and who obey Christ. These have the right to enter the city, for no sinner can enter there.
