But store up for yourselves treasures in heaven, where moths and vermin do not destroy, and where thieves do not break in and steal. (Matthew 6:20 NIV)
Everything in this world passes away. Whether ourselves naturallly or thing through decay. Fortunes are made and lost. Relationships come and go. Everything is fleeting.
However, when we look beyond ourselves to our spiritual life and to the lives of others where something lasting can be built. When we invest in these two things we leave a legacy and we prepare for what is beyond this life.
