A mighty boast got me thinking:

“I deal with the White House. I deal with Tony Blair. I deal with presidents around the world. I pastor a multimillion-dollar congregation.”

 – Eddie Long, pastor of New Birth Missionary Baptist Church in Lithonia, GA

Shall the axe boast over him who hews with it, or the saw magnify itself against him who wields it? (Isa 10:15)

God uses Satan to carry out His will (Job 1,2; 2 Sam 24:1, 1 Chr 21:1)
He used Joseph’s jealous brothers (Gen 50:20)
He used Pharaoh (Ex 9:16)
He used the Pharisees (Mat 26:5, 17, 47; John 11:50-52)
He used Judas (John 13:27)
He used Pilate (John 19:10,11)

Every good work that men do has been laid out ahead of time (literally) –

For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them.

Since even boasting about being used by God is out of the question, in what shall we boast?

Let the one who boasts, boast in the Lord.
