I agreed with you!! Many cultures even here will banned him with such shoe on his foot! You make him accepted where he was been banned before!! You are really kind towards this man! It is easy said than done! You are doing the practical expect which God urges us to do!
Sometimes ago, during service in our church, a man came in with dirty cloth and bad shoe's on his foot, everyone was running away from him, myself and one woman was the one waiting, this scene almost stop the service, its not really easy with odour very worse, but this man was so meant listing to what the Rev'd was saying, I was just Stay alart should he want to make a funny move so I could run as well hehehe, not long before he went outside and went his way!
I remember a man of God which I read about him (Joseph Ayo Babalola), he usually invited sick, mental illness, epileptic, seizures etc immediately they got healing from God, they give life to God.... I hope this man was still alive.
Some Churches nowadays, rejected people like this, I must commend your efforts and kindness towards little John.
God bless you!!!
