What are you relying on, what are your basis for doing what you do? Your friends? Some great professor? Some great religious person? Your own observations and reasoning? Trickier might be, that you are going by what the present culture is teaching or perhaps what some famous radio or TV personally promotes/teaches. Or, perhaps unknowingly you are relying on what Hollywood is producing. God has provided everything for a powerful Christian life but an ever-deepening know of Christ is needed.
Peter warns his readers there will always be those who twist the scripture but they must not be carried away into error. In the midst of walking the difficult path of painful, frustrating and often threatening earthly existence, believers need both perspective of the end of the world and growth in their knowledge of Jesus and His grace for them. Believes are to be steady growing and keep hoping in the coming Day of the Lord!
