There are many times in the Bible that Jesus says something will happen...not good things. This does not mean that they are sent  or approved by God, but he is saying He sees it will happen. This is a warning / a word of knowledge. Examples:

Jesus said offenses will come. He was saying exactly that. He knew they would come, He knew  and understood our humanity.He told us how to deal with them.

Jesus said that satan wanted to sift Peter, that He knew this (word of knowledge)... God in His goodness was giving Peter a heads up ..remember, this was before the victory of the cross. We now as believers have restored dominion and power over every attack.Before that, the Holy Spirit did not dwell in men , empowering them, but came upon them.

Paul was also warned by the Lord that because of the persecution of the  church, the enemy would be tormenting him and it would be a hard road, but He would and did deliver Paul and give him strength.The enemy has not happy that Paul was no longer under his control  of religion and the jezebel spirit.(that attacks God true authority in leadership)  This does not mean that GOD sent a tormenting life to Paul. But was indeed showing him what He knew then enemy would do...

Beloved, when things do not add up to Who God is,  a good God, full of mercy and goodness, we need to throw it out and not believe the lie about God. This is a a false image. We cast them down and stay true to He is. DO not let the enemy lie about Gods revealed nature.  Simply ..God is good and gives good things.This IS the finished work of the Cross.HE restored all things. He does not use evil, that would be a partnership with evil-  the same evil that Jesus came and conquered! Jesus came to destroy the works of the enemy, giving true believers the same anointing and demonstrations of power that He walked in.

Yes, attacks will come, because we all in in the process of renewing our minds, and need revelation. But God does not send them or stand by and simply allow them to happen without giving us the answer.! He gave us power and authority to stop them! The enemy wants people  to thinkthat God is using evil, but jesus came and did destroy the works of the devil.The only authority satan now has, is because we give him ours! We do this by wrong thinking, false images and by not doing anything...Complacency with our use of His authority over darkness.    Jesus is pure light , not a mixture of any sort.   AAF
