Grieving a loss of a loved one is personal, and I do not believe there is a magic formula. God is the only one that knows what you need.
There came a time in my grieving when I heard the Lord say that it was time for me to move on so that I could live by the will of God and not in the past.
“Brethren, I do not count myself to have apprehended; but one thing I do, forgetting those things which are behind and reaching forward to those things which are ahead, I press toward the goal for the prize of the upward call of God in Christ Jesus.” Philippians 3:13-14
