'Act' in the Bible

Thus we urged Titus that, just as he had previously begun this work, so also he should complete this act of kindness for you.

But as you excel in everything -- in faith, in speech, in knowledge, and in all eagerness and in the love from us that is in you -- make sure that you excel in this act of kindness too.

We are also ready to punish every act of disobedience, whenever your obedience is complete.
