Inspiration Thursday

We have a couple of friends and family members that are going through some very difficult times with health issues. One friend in particular has been battling an illness for over a year and the symptoms had gotten worse. They are losing sleep, have severe headaches, and symptoms that most of us would consider devastating to our physical and mental health. This situation also takes it's toll on the rest of the family.
As friends we want to be of some help. We are praying for the entire family and we want to offer words of encouragement, but what do you say? When the suffering is constant and the battle seems never ending. The usual verses of Scripture just don't seem to be adequate or appropriate for this situation. As Christians, we've heard, "All things work together for the good to those who love God and are called according to His purpose" (Romans 8:28). Those are easy words to say, but it's hard to hear them when your head has been pounding for weeks, and your body trembles on a regular basis. What promise of God can possibly speak to this situation? My wife found a verse for another family member that speaks to almost every need.  Again, we just need to remember that we serve the God of all creation and we are special in His sight. God is faithful and He will indeed walk beside you through the trial, but God never said that Christians would not face difficult days. God and God alone tells His children, "When you pass through the waters, I will be with you; and through the rivers, they shall not overflow you. When you walk through the fire, you shall not be burned, nor shall the flame scorch you. For I am the Lord your God. The Holy One of Israel, your Savior;..." (Isaiah 43:2-3)
