Why do Christians have sickness?

I am going to answer this from the Words of the Scripture on what our Lord and Savior taught the Apostle Paul about why Christians have sickness.  Paul said to the Corinthians:  “That's why so many of you are weak and sick and a considerable number are dying.”  This statement is to Christians, not Gentiles.  In a way, this is a very shocking statement. 

It says “many” are weak and sick.  Are there something these Christians did or not do to cause this.  Yes, in fact there is.  What were they doing to receive this type of instruction from Paul, but to celebrate the Lord’s Supper or as Jesus called it, Passover or Jesus Passover Service.  Jesus Passover was done with bread and cup on the night Jesus was betrayed, not on the night the Jews held their Passover.

This is what Paul was referring to, take the Passover in unworthy manner,  person must examine himself, because whoever eats and drinks without recognizing the body, eats and drinks judgment on himself.  If we recognize we are unworthy and are sinners, then we need to take the Passover. If we really do not recognize this, then when we take the Passover, we bring judgment on ourselves.  Now, Paul tells us, that is why many of us are weak and sick and a considerable number are dying.  Jesus said the bread is His body.   Isaiah said by his stripes we are healed.  When we partake of the Passover each year, we are to examine ourselves.

That's why so many of you are weak and sick and a considerable number are dying.  (1Co 11:30)

When you gather in the same place, it is not to eat the Lord's Supper.  (1Co 11:20)

1Co 11:23-29  For I received from the Lord what I also passed on to you—how the Lord Jesus, on the night he was betrayed, took a loaf of bread,  (24)  gave thanks for it, and broke it in pieces, saying, "This is my body that is for you. Keep doing this in memory of me."  (25)  He did the same with the cup after the supper, saying, "This cup is the new covenant in my blood. As often as you drink from it, keep doing this in memory of me."  (26)  For as often as you eat this bread and drink from this cup, you proclaim the Lord's death until he comes.  (27)  Therefore, whoever eats the bread or drinks from the cup in an unworthy manner will be held responsible for the Lord's body and blood.  (28)  A person must examine himself and then eat the bread and drink from the cup,  (29)  because whoever eats and drinks without recognizing the body, eats and drinks judgment on himself.

(Isa 53:5 KJV)  But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed.
