In those Eucharistic miracles you mention, the saints/blesseds received/welcomed the Host.
In Sr. Faustina's vision, she kept returning It to the tabernacle, as though she were not in need of It or not worthy to receive It, which she certainly is, especially if she is sinless (because she apparently escapes God's judgment and is more united to Jesus than any other creature).
I do not know why. What I do know is that the love that Jesus has for each of us is a special love, it is not a "one size fits all" love.
Most of the time the gifts that god gives to the soul are spiritual and they cannot be described in human terms unless God permits it.
Poche, you have a tendency to make statements which are unnecessary, because nobody argued the contrary, implying but not openly stating, that your opponents actually believe the contrary. This is the argumentation style of the modernists. It is misleading, confusing, and dishonest. I'll give you an example. "God does not have a one size fits all love for us." You deny that which was never proposed, thereby implying that the belief is secretly held. I've heard Bergoglio speak the same way. It is jarring to the ears.
