Yesterday, I read Matthew 5:14-16, Christ's words: “You are the light of the world. A city set on a hill cannot be hidden. 15 Nor do people light a lamp and put it under a basket, but on a stand, and it gives light to all in the house. 16 In the same way, let your light shine before others, so that they may see your good works and give glory to your Father who is in heaven."
A few verses later, Matthew 6:1-4, “Beware of practicing your righteousness before other people in order to be seen by them, for then you will have no reward from your Father who is in heaven. “Thus, when you give to the needy, sound no trumpet before you, as the hypocrites do in the synagogues and in the streets, that they may be praised by others. Truly, I say to you, they have received their reward. 3 But when you give to the needy, do not let your left hand know what your right hand is doing, 4 so that your giving may be in secret. And your Father who sees in secret will reward you.
It's all about motive. Is it 'in order to be seen' or is it 'so that they will 'give glory to your Father who is in heaven'?
TREASURES
“19 Do not lay up for yourselves treasures on earth, where moth and rust destroy and where thieves break in and steal, 20 but lay up for yourselves treasures in heaven, where neither moth nor rust destroys and where thieves do not break in and steal. 21 For where your treasure is, there your heart will be also."
Christ sees the foolishness in our prizing earthly things. We rarely do. On our death bed, maybe.
