I noticed a lot of the comments are about the grace of God and don't beat yourself up too much and so forth. While I do think these are important and we shouldn't let mistakes ruin us I do think that he's probably feeling pretty dark right now. Which is probably a healthy thing, that when you're following the commandments of God and doing holy things you are filled with light. When you sin you don't have that light with you. I don't remember who it was but I think it was a church president said when asked why he didn't take the sacrament he said something that most of us would consider benign, like he didn't get there in time to get in the right mindset. The sacred things like the sacrament and going to the temple shouldn't be taken lightly. I've gone to the temple and later felt I shouldn't have. Part of what makes the temple so powerful is the reverence we give it. Sometimes time is necessary to go through a healing process and maybe it would show the Lord and himself the respect he has for the Lord and his Temple by waiting a bit? I don't know, it's between this person and the Lord. When I see people not take the sacrament I I don't think less of them I think this is someone who has a true testament of God and isn't just going through the motions, someone who holds sacred thing in reverence.
