Oh and by the way, suffering is one of the side effects of sin
(a free will to disobey and turn away from God). Remember Scripture
said that the wages of sin is death (Rom 6:23a)? Suffering is just
a lesser evil of death.
Just because human sinned through Adam, God has laid down his plan
right from the beginning to send His only Son, Jesus, to die for
all of us. And that is why we believe Jesus is our Lord and
Saviour.
Just take it this way. God, in His infinite Grace and Glory,
created human in His image and likeness. Humans are supposed to be
in the bosom of God, inheriting all the Grace from God. With all
and fullness of Grace, human was supposed to be sinless. However,
when Adam disobeyed God, Adam deliberately cut off himself from
God's Grace. With absence of Grace, sin enters to mankind.
So, God did not create suffering. Human (Adam) chose to sin, hence
suffering follows. God also did not create death. Because of
disobedience of Adam, the punishment is death. God warned us (read
Gen 2:17 and check it out)!!
