I know it’s painful to say goodbye, I know it hurts to never see them again, but if there is faith in your heart you will know that God is taking care of business His way.
We are His children, He is our Father, He created us, He made us, He giveth, He taketh. Holding on to loved ones who are in their final days is not trusting God to take better care of them in death.
Holding on to loved ones means that they will hold on longer because they don’t want to see you grieve and ache for them. Holding on to loved ones means they have to endure more pain. Instead pray that God will take over and look after your loved one and give them new life as Jesus promised He would when He raised Lazarus.
