Nothing much I can think of at the moment to add to this goodly, informative thread but can offer this tidbit despite my understanding of ancient Hebrew and koine Greek being underwhelming: In instances where "Blessed" or "Happy" is mentioned in the Bible, both are correct given the context. "Happy", as I understand it, is the literal rending from the scriptural text. I can see the concern over using this word over "Blessed" given how modern readers may fail to see religious connotations in the current usage of the English language [talking about "Happy"]. This issue is simply resolved, regardless of which word is being used, when the expressed meaning is understood to represent that either of them is to be "divinely favored by God" or "having God's divine favor". Keeping blessed Mary in mind, this is also considered in the Gospels when she is conceived by the Holy Spirit to be the mother of Jesus, textual differences due to different faith traditions and interpretations aside. If further explanation is needed after this description, we then can say it's when we follow God's will in spite of having our own, observing His commandments respectfully without turning our faith into consciously following rules for the sake of rules. Don't get me wrong. Rules are good and need to be followed. What I'm saying is, it is better to honor them subconsciously, that we do them without thinking about them. We love them because of faith and through our faith rather than turning it into a calculated exercise that puts us front and center, because of our desire, instead of God. Psalm 119:97 KJ O how love I thy law! it is my meditation all the day.
