Have nothing to do with them.

(J. C. Philpot, "New Years' Addresses") "They mingled among the pagans and adopted  their evil customs. They worshiped their idols,  and this led to their downfall." Ps. 106:35-36 The 'carnal professors' of the day see nothing wrong, nothing amiss, nothing inconsistent in their conduct or spirit, though they are sunk in . . .   worldliness,   carnality, or   covetousness. But where there is divine life, where the blessed Spirit moves upon the heart with His sacred operations and secret influences, there will be light to see, and a conscience to feel, what is . . .   wrong,   sinful,   inconsistent,   and improper. It its but too evident that we cannot be mixed up with the professors of the day without drinking, in some measure, into their spirit and being more or less influenced by their example. We can scarcely escape the influence of those with whom we come much and frequently into contact. If they are dead, they will often benumb us with their corpse-like coldness. If they are light and trifling, they will often entangle us in their carnal levity. If they are worldly and covetous, they may afford us a shelter and an excuse for our own worldliness and covetousness. Abhor that loose profession, that ready compliance with everything which feeds the . . .   pride,   worldliness,   covetousness,   and lusts of our depraved nature, which so stamps the present day with some of its most perilous and dreadful characters. "Having a form of godliness but denying its power.  Have nothing to do with them." 2 Timothy 3:5 link
