To tempt is to lure or entice. You might tempt your runaway dog back inside with pieces of cheese.
The verb tempt often has negative implications: "Don't let those bullies tempt you into picking on smaller kids!" When something tempts you, it's often with the knowledge that it's not the best idea, however attractive it might be. Tempt was originally a religious term, meaning "to entice to evil or sin," while today it's more likely to be a slice of cake that tempts us than the devil.
