Philippians 3:20-21

v20: Remember "this world is not our home," heaven is.  It is where our Saviour is now, and it is where we hope to be soon.

v21: When Jesus returns, we can be certain that our bodies will be transformed into glorious bodies.  We can have this assurance because "we not only have the Scriptures, which assure us it will happen," but also we know the power of God is able to carry this out, because it already has in raising Jesus from the dead.  "His resurrection is constant evidence of ours as well as a pattern of ours."
