46 Then a dispute arose among them as to which of them would be greatest. 47 And Jesus, perceiving the thought of their heart, took a little child and set him by Him, 48 and said to them, “Whoever receives this little child in My name receives Me; and whoever receives Me receives Him who sent Me. For he who is least among you all will be great.” (Luke 9:46–48, NKJV)
One of the most notable aspects of the kingdom of God is its spiritual nature; It is not of this world (John 18:36). That nature is on full display in this passage, when a dispute erupted among His disciples about who would be greatest in the kingdom. With a child beside Him, Jesus explained the heart of those in His kingdom will not prompt personal promotion above others, but humble deference to others. Christians are to treat each other with humility, considering others better than ourselves (Philippians 2:3-4). Oh, how many disputes in the church, in the home and with our neighbors could be avoided with such hearts within us! Unless we have humble hearts to receive one another, we cannot receive the Son or the Father who sent Him. Let us endeavor to love our brother (whom we have seen), so that we may love God whom we have not seen (1 John 4:20). Without question, “The kingdom of God is within you” (Luke 17:20-21).
