What was Jesus’ purpose in coming to earth?
For this purpose the Son of God was manifested, that he might destroy <loose, break, unloose, destroy, dissolve, put off, melt, break up, break down, annul, subvert, to do away with, to deprive of authority> the works <anything which he undertakes to do>,of the devil.

Ga 3:10 For as many as are of the works of the law are under the curse: for it is written, Cursed [is] every one that continueth not in all things which are written in the book of the law to do them. 13 Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed [is] every one that hangeth on a tree:
Since calamity, disease, plagues and more are the result of sin, then there are results of sin when there is no sin. It may not be our sin, but the sins of others.
