[T]here is nothing I would not do for my children in righteousness. There is no river I wouldn’t swim, no mountain I wouldn’t climb, no terror I wouldn’t confront or beast I wouldn’t wrestle to the ground for my children. If “average, old Jeff Holland” can do and feel that, what on earth does it mean about our Father in Heaven and His love, what He would do and what He has already done?

As mortals, we tend to think that we can love someone with "all our heart". For example, I love my children with all my heart. That's just how I know how to describe that love. But...my love for my children, my wife, and for another is imperfect. There is still a mortal component to that love. Most of that component is my pride and selfishness, which doesn't allow me to be completely selfless, as much as I want to. It's just not possible in this life. And, it's not possible to even understand what it means to love another perfectly. I have an idea that I think allows me to understand, but my ideas, my understanding is severely limited, so I really don't know.
Imagine, then, the perfect love our Heavenly Father has for each and every one of us. We can't completely understand that love, but based on comparing that love with my mortal understanding of what love is and how much I can even love another, I have somewhat of an idea. But....all the love I can muster for another is still only a teeny tiny fraction of the love He has for me, and for you. His love for me is infinitely greater than my own love for my children.
Infinitely! That means there is no limit, no cap, to His love for me. I can't even fathom that because my finite mind always puts a limit on everything. Everything has an end, in my mind.
This brings some insight to John 3:16. Because of that perfect, infinite love for every one of us, He gave us His Son to teach us, to guide us, to protect us, to suffer for us, to die for us. And knowing a little bit of how infinitely He loves us and loves His Son, does that open the eyes a bit wider and give a different perspective? It does for me.
