You're a good Christian trying to live life as Christ would want you to and despite a few stumbles every now and then, for the most part, you're doing OK.
You meet another Christian, in Church, at work, at the tennis club or perhaps on the Internet.
That person too is a good Christian, like you, trying to live up to Christ's Word and be an example to others.
Somehow, the two of you fall out a little, you don't see eye to eye on certain matters; Liturgy perhaps, or Vatican II, or interptretation from the Bible. Slowly relations cool down to the point where you don't talk anymore.
Years later, you meet up in Heaven.
Do you pick up the argument where it left off and try to prove, with evidence from Jesus and the Saints, that you were right all along?
Or do you rejoice in what unites you rather than dispute over your differences?
If the latter ... then why wait until you're in Heaven to do it?
