Friend, we suffer and die because of SIN.
You say, "I didn't do anything wrong. Why am I a sinner?" We are all born with a sin nature. We inherited our fallen sin nature from Adam and Eve. Romans 5:12 says, "Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned:" We read in Romans 3:23 that ALL HAVE SINNED and come short of the glory of God. Why do we suffer? We suffer because we are sinners by nature.
Some People Suffer for the Salvation of Lost Souls
Perhaps you are thinking, "Well, what's the point? What does God accomplish by allowing us to suffer?" Very simple: He's trying to tell us something. By allowing people to suffer, God is showing us that SOMETHING IS WRONG. If everything were alright between man and God, then there would be no sorrow and death, because in the beginning there was none. God is showing you every day of your life that man has been SEPARATED from Him because of sin, and that man is destined to an eternity in Hell Fire unless he comes to God for help. The fact that God allows suffering and agony today proves that He will allow it in eternity as well.
God doesn't ENJOY seeing anyone suffer, but He does ALLOW people to suffer for various reasons. If you've never received the Lord Jesus Christ as your Savior, then God wants you to see your need to do so. Sometimes God has to allow tragedy to enter a life in order to get someone to look to Him for Salvation. As someone has said, "Some people won't look up to God until He puts them on their back." This is sad, but true. There are many people who would still be lost in their sins if God had not brought some tragedy into their life to get their attention.
Do you suppose the leper of Matthew 8:2 would have came to Jesus if he'd been in perfect health? What about the blind man of Luke 18:35? II Kings chapter five tells the story of Naman, the Syrian captain who had leprosy. Had this man not had leprosy, he would never have turned to God. The Bible is filled with cases where God reaches people through suffering. Nebuchadnezzar didn't fear God until God humbled him by making his spend seven years of his life on his hands and knees like an animal (Dan. 4:30-37).
Sometimes He will even use the tragedy of one to bring OTHERS to Christ. Such is the case with Lazarus in John chapter eleven. Lazarus was very sick, but before he ever died Jesus said that his sickness was "for the glory of God" (Jn. 11:2-4). Later, in John 11:45, we read that ". . . . many of the Jews which came to Mary, and had seen the things which Jesus did, believed on him." We also read in John 12:11 that many believed on the Lord Jesus Christ BECAUSE OF LAZARUS. Had Lazarus not suffered and died, these people may never have come to know the Lord Jesus Christ. You see, God was in complete control. Jesus KNEW that Lazarus was sick, but He chose not to go and heal him (Jn. 11:6). He had a REASON for the sorrow and death in the family of Lazarus. No one suffers in vain. God always has a reason, and sometimes He is trying to show someone their need to receive the Lord Jesus Christ. Could this be true in your own life? Think about it. Could the Lord be convicting you of the fact that you are a sinner, and you need to be saved?
