Your family has my deepest sympathy. I am so sorry for your loss. Mr. Koehn will be dearly missed. Though now you are grieving, please remember that you are not alone. Psalm 46 : 1 says, " God is our refuge and strength, a help that is readily found in times of distress. " Pray to Him for strength. He will really help you ( Isaiah 41 : 10 ) because He cares for you ( 1 Peter 5 : 7 ).
