What is Facebook good for? Provoking envy, according to studies.
Why are we humans so prone to brag, show off and flaunt pride? This is sin.
Why are also vulnerable to feeling envy? Rom. 12:15 describes Christian character: Rejoice with those who rejoice; mourn with those who mourn. Feel good about another’s success/blessing. Feel compassion on another’s failure/suffering.
Compassion of the suffering is why Christians evangelize. Maybe what you’re suffering is envy. Come to Jesus.
