Jesus said unto him,
You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.
All Commentaries on Matthew 22:37 Go To Matthew 22
John Chrysostom
AD 407
For since the first commandment was this, You shall love the Lord your God, thinking that He would afford them some handle, as though He would amend it, for the sake of showing that Himself too was God, they propose the question. What then says Christ? Indicating from what they were led to this; from having no charity, from pining with envy, from being seized by jealousy, He says, You shall love the Lord your God. This is the first and great commandment. And the second is like this, You shall love your neighbor as yourself. Matthew 22:37-39
But wherefore like this? Because this makes the way for that, and by it is again established; For every one that does evil hates the light, neither comes to the light; John 3:20 and again, The fool has said in his heart, There is no God. And what in consequence of this? They are corrupt, and become abominable in their ways. And again, The love of money is the root of all evils; which while some coveted after they have erred from the faith; 1 Timothy 6:10 and, He that loves me, will keep my commandment.
