1. 1 Timothy 6:10
"For the love of money is a root of all kinds of evil. Some people, eager for money, have wandered from the faith and pierced themselves with many griefs."
Paul identifies money's spiritual danger - not money itself but loving it. Barnes' commentary notes this doesn't mean money causes ALL evil, but excessive desire for wealth causes people to "wander away from the faith" and be "pierced through" with many sorrows. Gill suggests the warning applies when money is loved "above God" and becomes a form of idolatry. Meyer describes how "the denial of faith necessarily implies the denial of blessedness." The verse warns that pursuing money can corrupt spiritual commitments and create internal emotional suffering (BibleHub Commentaries).
