Here are some quotes on God's love. They are encouraging to me, and I hope they inspire you to love like God does.
“God loves each one of us as if there were only one of us to love.” (Augustine)
“While God is not pleased with my sin and may discipline me in order to turn me from destructive paths and practices, His love for me does not diminish in any degree. He gave himself for my sins in their entirety, so that I might have His love in its entirety… Accepting this reality of God’s unchanging regard is necessary for us to make progress in the Christian life.” (Bryan Chapell)
“In Himself, God is love; through Him, love is manifested, and by Him, love is defined.” (Burk Parsons)
“Christ died not in order to make God love us, but because He did love His people. Calvary is the supreme demonstration of Divine love. Whenever you are tempted to doubt the love of God, Christian reader, go back to Calvary.” (A.W. Pink)
“He loved us not because we are lovable, but because He is love.” (C.S. Lewis)
