Hebrews 13:8 states, "Jesus Christ the same yesterday, today, and forever." and in John 14:10 Jesus states, "Don't you believe that I am in the Father, and that the Father is in me? The words I say to you I do not speak on my own authority. Rather, it is the Father, living in me, who is doing his work."
So if Jesus is the same, yesterday, today, and forever, then the Father that lives in him is the same, yesterday, today, and forever.
Well coming to know God's love stays the same all the time, means coming to know God himself, which is revealed in the bible. God doesn't change. That is revealed to in Mal. 3:6.. he states that he does not change. We know that he loves us and always will that is why he made the greatest sacrifice on our behalf, by sending his only begotten Son Jesus. Jesus laid down his life so that anyone exercising faith in him can gain everlasting life. That is the greatest expression of Love that Jehovah and Jesus did for us.
Because he loves us, does not mean that he accepts or condons all types of behavior. How we conduct ourselves has an affect on him, and can make him happy or sad. The same way it does with us in human relationships. So many people today have confused the word love to make it means it is accepting of all things. That is not the love that God teaches and it is not the love that God displays. If you would like to get into more depth on this topic and come to know God as John 17:3 says, I would enjoy having a conversation with you. Or you can go to jw.org for more information.
