#1 "Jesus said to them, 'My food is to do the will of Him who sent Me, and to accomplish His work.'" John 4:34
#2 "Jesus answered and said to them, 'This is the work of God, that you believe in Him whom He has sent.'" John 6:29
#3 "'Do not lay up for yourselves treasures upon earth, where moth and rust destroy, and where thieves break in and steal. But lay up for yourselves treasures in heaven, where neither moth or rust destroys, and where thieves do not break in and steal; for where your treasure is, there will your heart be also.'" Matthew 6:19-21
Something about #3 that we (especially Americans) don't notice. Jesus said "Do not." He didn't say, "Go ahead and have treasures on earth as long as you aren't consumed by them."
It is something for us to think on. I think about these verses all the time.
