David, the psalmist, simply says that if you are merciful to others, if you lend yourself to others fairly and with good judgement, then you are merry. Accompanying your kind words and loving deeds is a happy heart.
The man is merry, that doeth mercy, and lendeth; he disposeth his words in doom; (Happy is the person who giveth favour when he lendeth; he disposeth his deeds with justice, or with good judgement😉
I wish I could say that people come up to me and ask me the reason for my “faith and hope.” I can’t. I can tell you people often comment on how happy I am – they do this because at work in the hospital as I walk between seeing patients, I sing or hum. People, as they pass, comment, “My you’re happy this morning.” And my response, most often, is: “Oh, I’m sorry. I didn’t realize I was singing out loud” or “I am happy, thanks.” Sometimes, if I’m not bubbling with true joy, I respond, “Might as well be happy.” I say this because for me happiness is a choice. I do choose to be happy. Life is too hard and too short not to make the very best of it. I admit I’d get a real kick if someone would actually stop and ask me why I am happy, why I have faith and hope as if that someone could see that in my demeanor. I know exactly what I’d say.
But hallow ye the Lord Christ in your hearts, and evermore be ye ready to [do] satisfaction to each man asking you reason of that faith and hope that is in you, but with mildness and dread,
