A man dressed in a $2000 suit can be just as dangerous if not more, than a person wearing rags. John Gotti was very well dressed. Bashar al-Assad also wears suits. Gotti was, and Assad is, a monster. If that man had of been wearing expensive clothes and a gold watch it would have defeated the whole purpose. God tests our faith. Maybe that was one. You have every right in the world to be cautious. There is much darkness in this world, but not wanting a seemingly indigent person in your church because of what you fear might happen isn't very fair. Should all less fortunate souls be denied access to a place of worship because of other bad apples that came before them? If so, why stop there? Perhaps we should condemn all of today's German citizens for Hitler's actions decades go also. I apologize for coming across as argumentative and I know that I am new here, but things like what you said annoy me. If a homeless person is intent on harming you or your loved ones, it won't matter if it's in a kitchen or a church. It's going to happen.
Who are we to decide who is and isn't allowed to walk into God's house? It would be absolutely awful if your fears came true and a homeless person was allowed in by the church members and hurt someone, but in your sorrow and anger, you could never be accused of not trusting your heart and doing your best to be Christlike. When you die, your decision to go with your heart is what will matter, not that monster who hurt the ones you loved. I'm not judging you. It's important to me that you all understand that. It's just how I feel about it.
