I describe my wife in the same way and share your grief and concern for her illness. The Gospels are filled with examples of Jesus’ love and compassion for those that are suffering, He is the divine physician and may his gentle touch heal your wife’s cancer.
Please keep my family in your prayers as well, we are also fighting illness.
Prayers up for both of you. God is by your side and I truly believe in miracles. May he comfort and strengthen both of you during these difficult times.
