One key to this relationship is simplicity

The earth is the Lord 's and the fullness thereof, the world and those who dwell therein. (Psalm 24:1 ESV)

From this, we understand that all that we “own” is actually owned by our Creator, which includes not just our possessions, but ourselves as well. We are simply stewards or caretakers of what God has put in our charge.
 Understanding the principles of ownership (that God owns everything), stewardship (that we are to use what God has given us in conjunction with His will and His Word), and the need for developing a proper relationship with possessions and finances helps us to adjust our attitude and behavior regarding those things that we have control over, both tangible and intangible.
 One key to this relationship is simplicity. Simplicity can be understood as a means of being freed from some of the unnecessary attachments to the things of this life, a means to set our minds on things that are above, not on things that are on earth.
 Jesus told us that our heart is where our treasure is; therefore it’s wise to examine what we consider our true treasure to be. We should have a right relationship with our possessions and recognize the damage that can occur if that relationship gets out of balance. Simplicity can lessen our focus on ourselves and our things and help to keep us focused on our true treasure, our loving God who has given us the most valuable things we could ever possess—His love and salvation. —Peter Amsterdam [1]

 Human beings who leave behind them no great achievements, but only a sequence of small kindnesses, have not had wasted lives. —Charlotte Gray
