Warning Others of Sin

But encourage one another day after day, as long as it is still called “Today,” lest any one of you be hardened by the deceitfulness of sin. (Hebrews 3:13)Encourage is from the Greek parakaleo, a form of the word used by Jesus of the Holy Spirit in John 14:16. The root meaning has to do with coming alongside to give help. The writer is saying to the believers among those to whom he is writing, “Get along side each other and help each other.” They are especially urged to help their unbelieving Jewish brethren by encouraging them not to harden their hearts but to accept Jesus as the Messiah. . . .
