My husband has similar problems, back pain (arthritis) and depression, and is also restricted, so I sympathize, and will pray for your Dad while praying for my husband. It’s painful to see your Dad suffering, and enduring that kind of frustration and loss of sense of purpose.
Jesus I ask Your blessing and help for this loved Dad. Please give him enjoyment of life and his family even so, and help him to fin a sese of acheivement.
Jesus, You are aware of all the difficulties that this family faces. Please give the Your help and support, and resolution where possible.
Thank You, Jesus
