Prayer for Faith & Healing

Our marriage and family has had two years of difficulty while considering separation. The husband has suffered with rheumatoid arthritis, herniated discs and has near constant pain. This affects the entire family including our three young children. The wife has recently seen her own selfishness and ungratefulness and has invited the entire family to allow more of Jesus into their lives daily. All are believers, but we've not prayed or read regularly as a family. Please pray for healing, both physical and spiritual, if it is God's will.
