The lazy tendency in us is to always choose to do nothing than to act on something.
To do nothing obviously will mean that we will also learn nothing and have nothing to gain.
To do something and to act upon something would mean that we will have to take the effort to think and to make decisions.
In the gospel, when the Risen Lord Jesus showed Himself to the Eleven, He reproached them for their incredulity and obstinacy, because they had refused to believe those who had seen Him after He had risen.
Not to believe in the Resurrection would be an easier option, though a lazy one, as there is no need to do anything since they don't believe it.
But if they believe, then it would mean that they get into action and see what the Risen Lord wants of them.
But with the Risen Lord Jesus appearing to them and reproaching them, they certainly had to get moving and going.
What we heard in the 1st reading was just one of the many instances of early Church in action.
May the Risen Lord Jesus also show us what He wants of us and may we get moving and going.
