The passage in Heb. 12:1 means that we are to personally apply discipline, and with divine help to thrust from us all temptations to carnal and worldly indulgence, which would impede our progress in the spiritual race. These obstacles are of the character mentioned in Mark 942-48; Eph. 4:22; Col. 3:9, 10. In practical terms, we should include undesirable and unprofitable amusements, doubtful associates, foolish pride, habitual ill-nature or worry, planning things far ahead, striving for social show for appearance's sake, deceitfulness, gossip, profanity, exaggeration or untruth—in a word, the "familiar sins," and especially the one which does "so easily beset us," whatever it may be. All of these act as chains and drags to hold us back.
