"...as sorrowful, yet always rejoicing; as poor, yet making many rich; as having nothing, yet possessing everything."
2 Corinthians 6:10 ESV
As Christians, the earthly materilistic possessions that will pass away should mean very little to us. In fact, if we were to have nothing, that should not matter because we already possess everything.
Almighty God, our Creator, has given His life to redeem ours. He has given us many titles; all of which we do not deserve. Here are some of them: children of light, friend, beloved etc.
Reader, does the very fact that God has given you those titles fill you with joy? Do you see why joy lasts even throughout poverty? God has given Himself for us to have a personal relationship with for eternity - purely out of His grace.
Surely, we truly possess everything.
