Prophet Ibrahim (as) was willing to sacrifice what was even more precious to him than his own life. Are we willing to sacrifice less precious things for the sake of our Lord? Are we willing to sacrifice some of our time, money, reputation and ego for the sake of God?
If yes, then we have a good reason to celebrate Eid today. If not then we can start working on our soul to make it prepared for such sacrifice; the decision to start, itself will be a good reason to celebrate the Eid.
So one way or another, we can have an Eid, either to celebrate an achievement or to celebrate the beginning of an effort towards an achievement.
