If you were of the world, the world would love its own. Yet because you are not of the world, but I chose you out of the world, therefore the world hates you. John 15:19 New King James Version
Many Christians mistake this to solely mean to those outside the Christian community like Buddhists or Muslims or New Agers.
From my experience, and I have a lot of it, they did not hate me. They either respected my beliefs, tolerated it or ignored it.
Then what could these verses be referring to?
Again from my experience, and I have a lot of it, it was from the false Christians in the church, particularly the wolves (the self righteous ones who are always quick to find fault and condemn others). They put on the façade of being a Christian during the sermon but were the biggest hypocrites before and after the service. They do more to give Christians a bad name and drive others away from Christ and church than the best of Satans minions. When they see Christians they hate us and constantly make false accusation against us and do everything they can do to make our life difficult.
So do not be surprised when your worst attacks come from within the church and not outside it.
“Blessed are you when they revile and persecute you, and say all kinds of evil against you falsely for My sake. Rejoice and be exceedingly glad, for great is your reward in heaven, for so they persecuted the prophets who were before you.” Matthew 5:11-12 New King James Version
Prayer: Please Jehovah Yehew (God of His people) bless me with the wisdom, strength and meekness (meekness means to keep our tempers under control so we do not fall into their wicked bait to get us into stupid arguments and make us look bad) to always exhibit the same behaviour as our beloved friend Jesus did when encountering the scribes and Pharisees in His time. Bless us with this opportunity to expose their evilness and Your divine love. I sincerely ask this in the name of He who showed the way Jesus Christ. Amen.
May the sunshine of Jesus’ sweet love bless you today and every day
