In I Corinthians 11:31 If we would examine ourselves first, we would not come under God’s judgement. Most everyone knows that there is a day set aside for the Great White throne, for the Final judgement. This judgement is for non-believers. If you are a believer in Christ Jesus, and repented from your sins you will not be judged for those sins because they have been washed away. But, if you do not repent from your sins, than the devil will get access to you by getting God to judge you. Remember he is the accuser of the brethren. Matthew 7:1 “Do not judge others, so that God will not judge you”
Let go back to Job 1:6,7 When the day came for the heavenly beings to appear before the Lord, Satan was there among them. The Lord asked him, “What have you been doing?” Satan answered, ” I have been walking here and there, roaming round the earth.” vs 8 YLT And Jehovah said unto the devil, ‘Have you set your heart against My servant Job because there is none like him in the land a man perfect and upright, fearing God, and turning aside from evil?’ vs 9-11 Then Satan answered the Lord, “Does Job fear God for nothing? Have You not put a hedge around him and his house and all that he has, on every side? You have blessed the work of his hands and his possessions have increased in the land. But put forth Your hand now and touch all that he has, and he will surely curse You to Your face.” vs 12 AMP Then the Lord said to Satan, “Behold all that Job has is in your power, only do not put your hand on the man himself” So Satan departed from the presence of the Lord.
God already knew Job was not under his protection any more, because of fear and judging others. Satan came to God to accuse Job, God had to make a judgment against him, which gave Satan access into Jobs life. Some people Think that God, was allowing Satin to do this to prove Job was trustworthy. God doesn’t have to prove anything to Satan. He’s not going to allow bad things to happen to His Children just to say, ‘I told you so Satan.’ God is love, but He has to be fair to everyone, He said in His Word, ‘if you judge others you will be judged.’
This is one answer to the question, ‘Why bad things happen to God’s Children?’
