We may not "notice it" so much (at first) or reflect on it beyond the particular "practices" that we take up as the most obvious dimension of our response to him. Our feelings about ourselves and our lives do not necessarily become warm, fuzzy, and comfortable, or exhilarated and self-consciously zealous. Or perhaps, we have an initial emotional enthusiasm that doesn't continue in the same way after a while. We certainly do not find our actions instantly rendered coherent with everything Jesus preaches in the Sermon on the Mount.
Nevertheless, the Spirit is at work in us, inviting us to move forward on the path toward God's kingdom, and also healing us and deepening our adherence to Christ in mysterious but very real ways.
Msgr Luigi Giussani always emphasized the impact of this change on our humanity. The journey of faith makes you a new creature, who has "the dignity, the certainty of your destiny and the capacity to operate in a new and more human way." This new humanity means "A different experience of the sentiment of yourself, a different perception of things, a different emotion of the presence of others, a different impetus and density in relationships, a different gusto in the troubled dynamic of work, an outcome that was inconceivable, unimaginable before."
