Are you saying that the parent-child interaction is not a relationship of love? Don't they both love each other to their fullest capacity? As you mentioned before about the woman who gave two cents, it is not a matter of how much, but the value of the gift to the giver. If we give our all, it is still meaningless, strictly speaking, to God. But it is worthwhile to God BECAUSE of His love for us. Does this mean, then, that we don't have a relationship with God?

The father-child example is an analogy, of course, and must be taken as such, not a parallel and miniature model of God's love for us.
I think I have answered this the first time quite correctly: relationship means being related to something. Inasmuch as man was created in His image and likeness, we are related to Him (although now only in His image), deficiently, as long we remember that imnage and likeness is a similitude and not the real thing; as much as a photograph of a person is related to the person it represents.
Inasmuch as our Lord is also fully Man, we are related to Him in our humanity. But His Humanity is pristine and ours is at the opposite end; a distant relationship indeed, shall we say a stretch, for comparative purposes, like comparing the relationship one finds between Mother Teresa and Australopithecus?
Inasmuch as His love is concerned, ours is nothing; some people have difficulty giving up 90 minutes on a Sunday to God but have no difficulty asking and hoping for a salvation lasting an eternity. Inasmuch as His suffering and gifts are concerned, ours are equally lopsided.
Inasmuch as we conform to His likeness, we are quite off, don't you think? Inasmuch as His goodness is concerned, that we take credit for, it is really all His, and none ours. Inasmuch as our life is concerned, it is His. Inasmuch as our existence is concerned, it is only through Him that we exist.
Inasmuch as His thoughts are His and not ours, and His ways His and not ours, we are not related to Him since what we think and do is not even an imitation. Inasmuch as our love for Him is concerned, it is mostly lip service for none of us will give up everything and follow His steps. None.
I am sorry but I really don't see much of a relationship in this; it is all His doing.
