We must take heed to what we have learned in the past (Heb. 2:1). There is a danger in drifting away from the truth (Heb. 2:2, 3). Therefore, we must be reminded of the things we already know (1 Cor. 4:17). One thing we need to remind ourselves, and teach to our neighbors, is the basic truth about New Testament Christianity. There is a lot of false teaching out there and people have the wrong concept (Matt. 7:15-20). It is our duty to expose it and teach them the truth (Eph. 5:11). This lesson will notice that New Testament Christians: (1) Believed in Christ; (2) Submitted to the plan of salvation; (3) Were just Christians; (4) Were not part of any denominations.
