Genesis 50:20 (KJV) But as for you, ye thought evil against me; but God meant it unto good, to bring to pass, as it is this day, to save much people alive.

This is the explanation to why Joseph went through all this hardship. In other words suffering to salvation. There are so many examples in the Bible of this. This includes GOD’s plan of salvation with Jesus Christ suffering on the cross for the salvation of all who will believe in Him.
“Luke 24:46-47 (KJV) And said unto them, Thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day: [47] And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem.”. “John 3:16-18 (KJV) For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. [17] For God sent not his Son into the world to condemn the world; but that the world through him might be saved. [18] He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.”.

Therefore let us be encouraged to persevere when we go through hardships. Even the process of hardship is for our benefit. “James 1:2-4 (KJV) My brethren, count it all joy when ye fall into divers temptations; [3] Knowing this, that the trying of your faith worketh patience. [4] But let patience have her perfect work, that ye may be perfect and entire, wanting nothing.”. In the end it will result in salvation for others. “John 12:24 (KJV) Verily, verily, I say unto you, Except a corn of wheat fall into the ground and die, it abideth alone: but if it die, it bringeth forth much fruit.”.
