2 Peter 1 talks about the promises of God.  Peter tells us that God has given us everything we need for a godly life.  Do you feel that way?  Do you feel like you have everything you need?  Some people have a scarcity mentality - they never have enough.  But, the Bible encourages us to have an abundance mentality - you have everything you need.  Peter says respond to this in the way you live, and know that the words in the Bible didn't just come from people.  They came from God.  God has given you everything you need.
