Paul: "Anathema" those who alter the Gospel

I love the language by Paul in Galatians 1:8: "But even if we, or an angel from heaven, should preach to you a gospel contrary to what we have preached to you, he is to be accursed!"

The original (Greek) word for "accursed" is "anathema" which means: something pledged (given up) to destruction; a divine curse/ban; an "oath-curse.". (Strongs 331)

Then Paul repeats himself in 1:9 and finally, if that were not enough, in 1:10 he asks the question: "For am I now seeking the favor of men, or of God? Or am I striving to please men? If I were still trying to please men, I would not be a bond-servant ("doulos" = slave) of Christ. (NASB)

Joel Osteen, and anyone who alters the Gospel of Jesus, is a slave of man; not Christ.
