John Wesley on Matthew 18:10

See that ye despise not one of these little ones - As if they were beneath your notice. Be careful to receive and not to offend, the very weakest believer in Christ: for as inconsiderable as some of these may appear to thee, the very angels of God have a peculiar charge over them: even those of the highest order, who continually appear at the throne of the Most High. To behold the face of God seems to signify the waiting near his throne; and to be an allusion to the office of chief ministers in earthly courts, who daily converse with their princes.
