It has taken science, in the fields of Psychiatry and Psychology, thousands of years to catch up to this passage. In Psychological terms, this would be stated as : “Children would rather be disciplined than ignored.” Its true.
The human soul, made to love God and be loved by Him, languishes in torment when it does not even receive God’s appointed tributary means through the love of other humans. Oh how we hate one another when we will not respond at all. We’d rather have open and humiliating rebuke, than to be so disregarded as to not even warrant that.
How painful then is hidden love. Perhaps you love your spouse, child, parent etc. – but do THEY know it? Do they have proof positive from you? Do YOU tell them and show them – not leaving either of those two necessities unexpressed?
As we take on the image of Christ, more and more we are bidden not to disregard anyone – but to love them, and so as to make them know it is love. God not only providentially cares for us, He speaks His love to us in His Word. We must have both.
