Jealousy
nPhilippians 1:15-17 (NIV) It is true that some preach Christ out of envy and rivalry, but others out of goodwill. 16 The latter do so in love, knowing that I am put here for the defense of the gospel. 17 The former preach Christ out of selfish ambition, not sincerely, supposing that they can stir up trouble for me while I am in chains.
n1 Timothy 6:3-5 (NIV) If anyone teaches false doctrines and does not agree to the sound instruction of our Lord Jesus Christ and to godly teaching, 4 he is conceited and understands nothing. He has an unhealthy interest in controversies and quarrels about words that result in envy, strife, malicious talk, evil suspicions 5 and constant friction between men of corrupt mind, who have been robbed of the truth and who think that godliness is a means to financial gain.
