One of my favourite verses about love in the Bible was found in 1 John 4:19.
“We love because He first love us”.
It is not from our own doing that we are able to love, but God demonstrated love by giving up His only begotten Son so that we could have life and to have it in full. And because of what Jesus did on the cross, I couldn’t think of any reason why I couldn’t fall in love with Him. Thank You, Jesus, for loving me that while yet I am still a sinner, you have died for me.
