2 Peter 1:3-4 Do you ever feel a little gypped? We used to have a little phrase that expressed that idea. From time to time you would here a person say 'I feel a little short changed'. It was a metaphor taken from the store keeper miscounting the change he/she was to return. It ended up being used as an expression when a person felt they had been cheated from something or gypped.
Rather than being 'shorted changed' in our Christian life, we have been 'amply supplied.' Jesus' divine power is the source of full provision for his children. His divine power has granted us all things that pertain to life and godliness through the knowledge of him who called us to his own glory and excellence.
We could add another 'p' word to the title- 'purpose.' Lest we think our salvation is solely for the purpose of escaping 'punishment' (another 'p' word), Peter says, no, the purpose of God's call is that we would exhibit his glory and excellence. God has called us to be examples of transformation. To make that possible He has granted, provided, made available, all the resources to make it happen. Those resources are found in His word, the indwelling Holy Spirit (who equips us by teaching, convicting, empowering to live the new life, by giving us confidence in our salvation), the body of believers (who build up). Interestingly the excellence spoken of comes as a result of making use of these resources. We 'short change' ourselves spiritually when we forego taking advantage of God's provision and strike out on our own. Let's value what he has provided.
