Everything is for a reason, may God be glorified.

Now a certain man was sick, Lazarus of Bethany, the town of Mary and her sister Martha. It was that Mary who anointed the Lord with fragrant oil and wiped His feet with her hair, whose brother Lazarus was sick. When Jesus heard that, He said, “This sickness is not unto death, but for the glory of God, that the Son of God may be glorified through it.” Now Jesus loved Martha and her sister and Lazarus. So, when He heard that he was sick, He stayed two more days in the place where He was. Then after this He said to the disciples, “Let us go to Judea again.” The disciples said to Him, “Rabbi, lately the Jews sought to stone You, and are You going there again?” Jesus answered, “Are there not twelve hours in the day?  If anyone walks in the day, he does not stumble, because he sees the  light of this world. But  if one walks in the night, he stumbles, because the light is not in him.”  Now Bethany was near Jerusalem, about two miles away. And many of the Jews had joined the women around Martha and Mary, to comfort them concerning their brother. Then Martha, as soon as she heard that Jesus was coming, went and met Him, but Mary was sitting in the house. Now Martha said to Jesus, “Lord, if You had been here, my brother would not have died.” Jesus said to her, “Your brother will rise again.” Martha said to Him, “I know that he will rise again in the resurrection at the last day.” Jesus said to her, “I am  the resurrection and the life.  He who believes in Me, though he may  die, he shall live. And whoever lives and believes in Me shall never die. Do you believe this?” She said to Him, “Yes, Lord, I believe that You are the Christ, the Son of God, who is to come into the world.”
