"Overcoming Jealousy"

“Love is patient, love is kind. It does not envy, it does not boast, it is not proud.“
Jealousy thrives in a climate of selfish ambition.
Jealousy is an insidious sin that cries out, “I want what you have, and furthermore, I don’t want you to have it.” It replaces contentment with resentment and spawns a myriad of other sins.
The Corinthians, in truth, were jealous of one another’s spiritual gifts. First Corinthians 12:31 literally says, “You are earnestly desiring the showy gifts, but I show you a more excellent way.” The word translated “earnestly desiring” is translated “jealous” in 1 Corinthians 13:4. It means “to boil” and speaks of the inner seething that comes from wanting something that someone else has. In 1 Corinthians 3:3 Paul rebukes them for the jealousy and strife that existed among them.
Paul knew what it meant to be victimized by jealous people. During one of his imprisonments he candidly wrote, “Some, to be sure, are preaching Christ even from envy and strife, but some also from good will; the latter do it out of love, knowing that I am appointed for the defense of the gospel; the former proclaim Christ out of selfish ambition, rather than from pure motives, thinking to cause me distress in my imprisonment” (Phil. 1:15-17).
Paul’s attitude toward those who envied him was exemplary: “Whether in pretense or in truth, Christ is proclaimed; and in this I rejoice, yes, and I will rejoice” (v. 18). He wasn’t motivated by personal comfort or selfish ambition. He loved Christ deeply and wanted as many people as possible to hear the gospel. As long as Christ was being proclaimed, Paul was happy—regardless of his own circumstances or the motives of others. That should be your perspective too.
Love is the antidote for jealousy. When godly love governs your heart, you can rejoice in the spiritual successes of others, even when you know their motives are wrong. But if you seek prominence and selfish gain, you become an easy target for jealousy and resentment.
