1 John 4:19 We love Him because He first loved us.
Our love for God is based off His love being revealed to us. We cant come up with the love of God on our own. I witnessed it 1st, recieved it, now Im able to give it out, in that order. This also tells me that God is the initiator of His love. He modeled His love to us. And since He did so, we know that if we love in His manner, its really Him who loves through us.
