1 Corinthians 15:33

Be not deceived. Or, “Stop being led astray.”

Communications. Rather, “companionships.” This is a line of poetry by Menander (343-c. 280), perhaps a common proverb. Since all are greatly influenced by those with whom they associate, the selection of friends and companions calls for great care. Paul exhorted the believers to beware of the smooth and plausible arguments of the false teachers who denied the resurrection of the dead. The company of such individuals is to be avoided. Association with those who hold erroneous opinions, or whose lives are impure, has a tendency to corrupt the faith and morals of believers. By daily association with those who did not believe in the resurrection of the dead, and by frequent conversation on that topic, the believers would be likely to lose their clear, positive understanding of the truth. Familiarity with error tends to remove objection to it and to lessen caution against it. For this reason God has always counseled His people to separate themselves from close association with unbelievers (see Gen. 12:1-3; Ex. 3:9, 10; Deut. 7:1-4; Isa. 52:11; Jer. 51:6, 9; 2 Cor. 6:14-17; Rev. 18:4).
