What is the sign of “valid ministry” in the Kingdom of God?

“You yourselves are our letter of recommendation, written on our hearts, to be known and read by all.” -2 Corinthians 3:2

Credentials have always been a big deal.  As a sign of legitimacy in any arena, recommendations from qualified people and certificates from reputable institutions have always been the mark of quality that most are looking for.

But the Kingdom of God has different criteria for credentials.

In the Kingdom, programs and achievements are important, and in many cases necessary, but they aren’t the most important thing.

In the Kingdom, what what matters most is not the projects you’ve accomplished or the positions you’ve attained.

It’s the people you’ve invested in for the glory of God.

So, how’s it going?
