Perhaps you have an extremely demanding job and are not home often, ask God to give you wisdom to live out this command in the midst of a hectic schedule. For you, it might mean one guest a month. Maybe you are a young mother and are spent at the end of the day. For you, it might mean inviting an unsaved mom over to befriend her and allow your kids to play. God cares about a heart that desires to minister, not duty for duty’s sake.
The past few weeks I have been taking a class on the ministry of hospitality at the Seminary. It is a class for wives of seminary students, and it has been extremely helpful. One of my assignments in class was to put together a devotion on hospitality, so I will be posting what I learned through this devotion in the next few days. God has really opened my eyes to what his vision of hospitality is in this class. Hope this helps!
