In all Christian understanding, almost nothing is more important than knowing how deep your trouble goes, and wanting healing and correction from your Creator:
When they heard this, they stopped objecting and glorified God, saying, “God has then granted life-giving repentance to the Gentiles too.”
(source: Monday of the Fourth Week of Easter)
Did I say almost nothing?
Right. There is ONE thing more basic, more important; ONE thing that comes before, behind, under, and ahead of our being and our becoming. ONE thing that makes it possible to see yourself as truly wicked and offensive, and truly beautiful and able to receive love.
DEUS meus, ex toto corde paenitet me omnium meorum peccatorum, eaque detestor, quia peccando, non solum poenas a Te iuste statutas promeritus sum, sed praesertim quia offendi Te, summum bonum, ac dignum qui super omnia diligaris. Ideo firmiter propono, adiuvante gratia Tua, de cetero me non peccaturum peccandique occasiones proximas fugiturum. Amen.
