On the surface, today’s passage does not offer a specific definition for the word hospitality, yet we are not left without clues. First of all, hospitality is something that is done “one to another.” This means that it is an action that should be done to other believers. It should also be done “without grudging.” Additional insight can be gleaned by considering hospitality’s root word, hospital. A basic definition for the word hospital involves a shelter for the needy or a place where the sick can recover. Thus, hospitality involves taking others in, even for a short time, to strengthen them in some area of need. Hospitality can be as simple as sharing a meal together or it may require more effort and time.
The Bible admonishes believers to be stedfast and unmoveable (1 Corinthians 15:58). We are to be grounded and settled (Colossians 1:23) in the faith—much like a tree planted by the rivers of waters (Psalm 1:3). Yet, today's passage points to the dangers of a hardened heart set in rebellion. It is likened to a stone and a millstone. We should remain stedfast in our commitment to serve the Lord, yet our hearts should remain tender and pliable to Him and His will. A stony heart hinders the seed of God’s word from taking root (Matthew 13:5-6). This hardness hinders the possibility of spiritual fruit from taking root and maturing. A soft heart and a stedfast walk exhibit the godly balance that God desires for each of us.
