"Say to them: 'The LORD bless you and keep you; The LORD make His face shine upon you, and be gracious to you; The LORD lift up His countenance upon you, and give you peace.' "
This famous benediction today only applies to those who sincerely love the Lord Jesus Christ, as they are gathered as His church. And what a wonderful pronouncement it is: we are given the assurance of God's favor, His protection, and His provision.
If you are a faithful churchman, then look less upon your own failings, and your sense of unworthiness; and look more upon Christ, who is determined to bless you (despite yourself). Recognize that the Lord does not bless perfect people; He only blesses redeemed sinners.
[Puritan quote of the day: "Christ gives to those who come to Him such comfort and pleasure as are enough to make them forget all their former labor and travail." --Jonathan Edwards, in the book, "On Knowing Christ"]
