When I regarded G-d as a tyrant I thought sin a trifle, but, when I knew Him to be my Father, then I mourned that I could ever have kicked against Him. When I thought that G-d was hard, I found it easy to sin; but when I found G-d so kind, so good, so overflowing with compassion I smote upon my breast to think that I could ever rebel against One who loved me so, and only sought my good.

Charles H. Spurgeon

It is not that we do not love G-d, it is that we love ourselves more.

"...you shall love the Lord your God with all your heart, with all your soul, with all your mind, and with all your strength.’ This is the first commandment." Mark 12:30
