It is always difficult to lose those close to us. Take heart and celebrate his life by keeping his ideals alive. I say this here, but you're already doing it by "introducing" him to us in absentia.
I don't quite know how to make this Hebrew phrase singular, to apply to one man rather than to many people, however the phrase is, זכרו לברכת (zichrona libracha), meaning, "May (his) memory be a lasting blessing."
I wish you and your family peace in this difficult time.
Im sorry that you are experiencing this. Last december we lost my father in law and pastor who was a major role model for me. I pray for your comfort. He lives on through you demonstarting what he taught you.
I`m so very sorry for your loss. I also congradulate you on your abbility to carry on. My wife is not in good health and I dont know how I will be able to carry on if something happens to her. Love your family, always treat them as if its your last day to see them. Time passes so fast and its not always kind. Prayers to you and your family.
