Of course it grieves me to see my family going through this, but my feelings do not make God's actions unjust. Look at it from God's point of view; a creation he made perfect was warned of the exact consequence of its actions, and then chose to defy God anyways. God is merely fulfilling His promise. He does not owe salvation to anyone, and would be perfectly just letting us all die in sin and burn in hell. However, in order to display the richness of His mercy, He chose to save some for reasons we do not know. Give me one good reason why my family member deserves to be saved? There are none. No one deserves to be saved. Give me one good reason why they deserve to be cast into hell? There are many, many reasons, but the chief would be the rebellion all men have against God.
Why pray for him? Because God commands me to do so. Will it have any effect? Of course! God promises to listen to the prayers of His people. I pray for him because God commands me to do so, and this is enough reason for me and should be enough reason for anyone else who claims to believe in Christ
But doesn't God love all the people He made? Doesn't God want us?
