I've been a Christian for 21 years. Exactly.
If you want the precise details it was about 8:30 in the evening, on Saturday 29th October 1988, somewhere about here:
“If our faith is such that it is destroyed by force of argument, then let it be destroyed; for it will have been proved that we do not possess the truth.” Clement of Alexandria, late 2nd Century
 Then we will no longer be infants, tossed back and forth by the waves, and blown here and there by every wind of teaching and by the cunning and craftiness of men in their deceitful scheming.  Instead, speaking the truth in love, we will in all things grow up into him who is the Head, that is, Christ.  From him the whole body, joined and held together by every supporting ligament, grows and builds itself up in love, as each part does its work.
 "Why do you look at the speck of sawdust in your brother's eye and pay no attention to the plank in your own eye?  How can you say to your brother, 'Let me take the speck out of your eye,' when all the time there is a plank in your own eye?  You hypocrite, first take the plank out of your own eye, and then you will see clearly to remove the speck from your brother's eye."Here, speaking the truth would involve the admission that "I've got a whopping big log in my eye". In other words, my problems are bigger than yours, I can't claim the moral high ground. And the 'in love' bit only comes into it because I'll only speak the truth about me in the context of a love relationship where I know I won't get abused because of it...
Therefore confess your sins to each other and pray for each other so that you may be healed. The prayer of a righteous man is powerful and effective.That's more speaking of truth in love. Wow. Does anybody do this in church these days? Not confessing your sins to the priest in the confessional, but to each other.
