Jonathan Edwards on the Christian’s love for God in this present age:
Grace and the love of God in the most eminent saints in this world, is truly very little in comparison of what it ought to be.
Because the highest love, that ever any attain to in this life, is poor, cold, exceeding low, and not worthy to be named in comparison of what our obligations appear to be, from the joint consideration of these two things; viz.
1. The reason God has given us to love him, in the manifestations he has made of his infinite glory, in his Word, and in his works; and particularly in the gospel of his Son, and what he has done for sinful man by him.
2. The capacity there is in the soul of man, by those intellectual faculties which God has given it, of seeing and understanding these reasons, which God has given us to love him.
How small indeed is the love of the most eminent saint on earth, in comparison of what these things jointly considered do require!
And this grace tends to convince men of; and especially eminent grace: for grace is of the nature of light, and brings truth to view. And therefore, he that has much grace, apprehends much more than others, that great height to which his love ought to ascend; and he sees better than others, how little a way he has risen towards that height. And therefore, estimating his love by the whole height of his duty, hence it appears astonishingly little and low in his eyes. – Religious Affections, in Yale-Works 2:325
