Formal Family Birthday Greeting

I need a polished, inspirational birthday message that I can deliver to a close family member. Please keep the tone formal yet warm, steering clear of casual slang or humor. The final text should run no shorter than three and no longer than five complete sentences, weave in a sense of pride and gratitude, and close with an elegant birthday wish. Once finished, provide the message in a simple text file so I can copy it directly into a card.
