There is another spiritual being at work in this world known as Lucifer or Satan. Satan was originally created by God as someone glorious, but having been created with Free Will just like you and I, Satan chose to become a prideful, rebellious, and evil spiritual being. Satan's goal is to deceive you into making the choice to serve and exalt him instead of God.
One of Satan's deceptive tactics is to cause people to bitterly blame God for the suffering that Satan's own demonic influences cause in the world.
An even worse deception is when Satan causes people to think they can never be forgiven for their rebellion and other sins.
Why does Satan want you to ignore and reject the salvation that Jesus has made possible?
...So that you will be captive in the same prison of
eternal anquish that is reserved for Satan and his demons.
