Myself, I have never had a devotion to the infant Jesus of prague.
I just don't see how people could adore Jesus by meditating on when He was an infant. His kingship is a manly one, full of wisdom and power, the infant to me represents a kind of Jesus that is weak and vulnerable, and under our power as any infant would be. Sorry if this offends, I understand it is a practice since before Vatican 2, but I don't think the church was free from error before the council either. Some people kiss that thing and practice idolatry.
I understand what you're saying, but reading up to this point, and considering some of your other posts, I think your attention and concerns are better focused elsewhere. I will promise you this. I will use this Infant of Prague, once blessed, and ask for your peace of soul and a Holy Death for you.
My point is Jesus and His glory was that He fearlessly preached the truth, was cruxified and rose again to be king. This infant represents before all this happened
This is true. And while not all devotions or prayers of Church tradition are imposed on the Faithful, people often have particular devotions to one or another (be it saints, prayers, etc).
Our basic catechism teaches us that God is Eternal. He has no begining or end. God is Trinitarian, containing three persons. Jesus, the second person of that Blessed Trinity, is God. Jesus is Eternal. Devoting oneself to the Eternal God, the second Person in the Blessed Trinity, we, as you rightly point out, speak to Him as our human minds only know how: as a person in a particular time; in reality, He is outside of time. But for our minds to comprehend what we can, we pick a particular time of His life on earth to meditate on and/or converse with him.
Our Blessed Lord was Lord and God during his Childhood, just as much as when He was an adult, and vice versa. Even his entire adulthood, He did not have a public ministry; but that did not make Him any less God before He converted water to wine for His Blessed Mother. It wasn't as if that was the moment, His first public miracle, that He had a new Nature. I'm sure others can speak more eloquently on this subject than I. But I want you to be assured of my prayers.
