Do never you wonder why God allows so much evil in this world? When there is so much fighting going on in the world we find it hard to believe that God is still in control. I got news for you he is still in control. The reason why there is so much evil in this world is because he has allowed Satan to believe that he's has taken over. Satan thinks he can win, but he can't. Satan doesn't have full control, God is holding him down. In order for Satan to have full control he would have to get rig of us the Christians. That's what he wants and he getting closer everyday to doing that. I believe that is impossible for him to do. If there is someway he can get us away from God he will.
Not everyone who says they are Christian is really a Christian. Satan is trying to get Christians to follow him by misinterpreted the scriptures, love of money, Sinning etc. Satan can never win, he would need to kill God to get rig of all the Christians. That will never ever happen. If you read the bible you will know that Jesus is coming back.
After Jesus has taken us out that's when Satan will get full control of the earth but only for seven years. It will be a time so evil that if anyone does become a christian they most likely will get killed. After that Jesus will rule the earth for a thousand years, there will be no sin. Jesus is coming back soon, how soon i don't know. God knows every little evil thing that Satan has planed.
God will use them to bring about his perfect plan. God is working everything out for us. Christianity will never ever die out. God has allowed evil to come into the work But he's still in control.
And we know that all things God works for the good of those who love him, who have been called according to his purpose (NIV)
