If anyone had a reason to stop believing in God because of pain and suffering and injustice, it was Jesus. Because the man who taught us that all people have inherent value and that all people are loved by God, was Himself treated with pain and suffering and injustice…and then executed…by those that He taught these things to. Think about that.
Pain and suffering and injustice are not rational arguments against the existence of God ~ certainly not the God that was presented to us by Jesus and other’s in the New Testament.
Satan has a pretty tight grip on you bud.
If you understand what Jesus taught then you understand that earth is not Heaven, there is no pain and suffering in Heaven, only here on earth. If you understand what Jesus taught then you understand that God's love is conditional, and the conditions are non negotiable.
You have to make the conscious choice to accept God, to have Faith in God, to love God more than yourself, and to do your level best to stop committing sins that you have control over.....in order to receive it.
There are rules, and those are God's.
Jesus taught that ALL people absolutely have that opportunity to recieve God's love in Heaven. Some choose to ignore that opportunity and carry on with their predestined condemnation. Satan loves you for that.
