"Now a certain man was sick, named Lazarus, of Bethany, the town of Mary and her sister Martha.
Therefore his sisters sent unto Him [Jesus], saying, Lord, behold, he whom thou lovest is sick.
When Jesus heard that, He said, This sickness is not unto death, but for the glory of God, that the Son of God might be glorified thereby.
John 11:1,3,4
Jesus wasn't talking about the problem; He was talking about the end result.
Jesus always talked about the end results.
He was saying the end result was that this sickness will not end in death but the glory of God.
In John 11:40, Jesus told Martha that if she believed, she'd see the glory of God.
The sickness took Lazarus' life for awhile, but his life was given back to him when Jesus raised him from the dead, which was for the glory to God and that He may be glorified.
