Almond Syiem, a blogger, recounts how his friend’s letter on his 50th birthday made his day extra special. He says, “As the day was winding down, I opened my email and found a letter from a friend who now lives in a different city… He, like a few other buddies, now separated by geography but connected through technology, is one of those people who refuse to judge me even when I rightly deserve to be judged but yet, at the same time, calls me to a higher standard that he knows he cannot attain without an enabling that is beyond him. He is someone who is very aware of his brokenness but who has also learned to live in the shadow of grace. I was deeply moved by his letter. His affirmation and encouragement, together with the celebration of our friendship, gave me great joy. Simultaneously, I was also impressed by the creativity of his thoughts as he typed his email to me (i).”
