If God is so powerful and knows everything. Why is there evil, suffering, pains etc in the world?
The purpose of God is to take a people out of the world throughout the history of mankind,to dwell with Him for all eternity giving them the joy of living forever with peace,love,and joy.
The Bible says that without God coming in flesh,He would of not created anything He created,for it is because of Jesus that creation is successful,even for the angels,for it is all made for people,especially the man Christ Jesus,and the angels assist in that purpose.
Some might say that they do not understand why so many people go through hurt,and suffering,so that God can have people dwell with Him for eternity,but mankind has a choice,and it is their bad choices that causes problems,and suffering.
The Bible says creation testifies there is a God,and of His attributes,which one of them is love,for He provided food,and the means to make clothing,and shelter,so the world is without excuse,which covers the 2 greatest laws,love God,and love people,which is the universal law whether people heard the truth or not.
It does not matter what problems are on earth,and what people go through,in the aspect that they can cry out to God,and be saved,and this world is temporary,and they will escape it when they leave this earth.
The things that happen on earth,the problems,sin,suffering,does not hinder a person from reaching out to God.
God gave Israel a blessing,and a cursing,for if they did right a blessing,that no enemy would control her,but if not than a cursing,her enemies would prosper over her,and scatter her in to the nations.
They could not touch Jesus until His time was come.
God's purpose is to give people a choice,to have people dwell with Him that made the choice to dwell with Him,and so there will also be evil,suffering,and pain,because of the bad choices people make.
It is because God wants people to dwell with Him for eternity,that made the right choice,that causes God to not step in and rule the world as He sees fit,for He gave people a choice,but one day He will cause all people that do not love Him,to follow a kingdom that is based on the occult,spiritual evolution,and believes in no personal God,and when they do then God will put them down,and the choice is over,and Jesus will take over the world,and then it will operate the way God always wanted it to operate,peacefully,where people will not war,and animals will be plant eaters,and will not fight with each other,and be so tame that a child can lead the most ferocious animal today.
If God did not give people a choice,then there would be no problems on earth,but there would not be salvation either.
