I have been wandering about this issue lately. Is it wrong to pray, for example the Rosary, when you have not yet repented of a sin? Often I am unsure if something I have done was a sin or not and I will promise myself to do a thorough discernment upon this later. It is left in something of a limbo. In the meantime, I pray the Rosary in other intentions. Lately I have been feeling that this is somehow wrong, that I should be approaching God and Our Lady with a clearer conscience. I hope this makes sense. Any input would be much appreciated.
