Charles Spurgeon Commentary 1 John 2:9

"He that saith he is in the light and hateth his brother, is in the darkness even until now." — 1 John 2:9 (ASV)

He that saith he is in the light, and hateth his brother, is in darkness, even until now.

God is love, and God is light; therefore, love is light, and the light of God is love. Where enmity and hatred are still in the heart, it is proof positive that the grace of God is not there.
