Ian Higginbotham looks at Jesus challenge in Luke 12:22-34.
This is part one of a two part message, part two is here.
The key verse for these message is found in Matthew 6:19-21:
Don’t store up treasures here on earth, where moths eat them and rust destroys them, and where thieves break in and steal. Store your treasures in heaven, where moths and rust cannot destroy, and thieves do not break in and steal. Wherever your treasure is, there the desires of your heart will also be.
During this message Ian refers to a Heavenly Treasure Conversion Formula, this is available on the second page of this document: Giving Balance Challenge
