Not at all.  I am very much at peace because I know (not just feel) that I am a child of God.

I understand what divine filiation means, and how to maintain a presence with God.

I can see why someone without a supernatural perspective might be inclined to come to that conclusion.

But I don't have that sense at all that you write about.  Not at all.

I know what joyful struggle is, as a child of God.

Read what the pope said just recently.

Joy is being close to God, and at times that means being with Him carrying the Cross, the happy cross.
