If using food ministry as outreach evangelism is effective, why did no one Jesus fed ever decide they’d be a disciple?
In all truth I tell you, you are looking for me not because you have seen the signs but because you had all the bread you wanted to eat. Do not work for food that goes bad, but work for food that endures for eternal life, which the Son of man will give you, for on him the Father, God himself, has set his seal. (Jn. 6:26-27) … After this, many of his disciples went away and accompanied him no more. (Jn. 6:66).
Feed hungry folk all you want. Just don’t imagine it will result in any spiritual growth.
