What Jesus said about treasures, the sound eye and serving of two masters in the the sermon on the mount

Treasures: Jesus
taught the multitude on the need to lay up treasures in heaven where moth and
rust will not consume and where thieves will not break in and steal. He warned
them against laying up treasure on earth where thieves and rnoth will break in
and steal. This admonition was necessary because where one’s treasures is,
there would be his heart also. 
Sound Eyes: Jesus was of the view that
the eye is the lamp of the body, Jesus taught them that if the eye is sound,
the whole body will be full of light. On the contrary, if the eye is not sound,
the whole body will be full of darkness,’they were to be careful that if the
light in them is darkness, the darkness would be awesome. 
Two Masters: Jesus
taught them that it is not possible for one person to serve two masters, since
he will either hate one and love the other, or be devoted to one and despise
another. Jesus admonished them to serve God rather than mammon. 
Misuse
of earthly wealth can lead to serious consequence for a nation. Going by Jesus
teaching, earthly wealth is synonymous with mammon and abuse of it leads to
extreme selfishness and Jack of concern for others and this will bring about
suffering to the entire nation. Outright use of earthly wealth leads to the
worship of materialism. When this happens, such a nation loses its spiritual
balance, becomes ungodly and gradually degenerates until it perishes like Sodom
and Gomorrah. Misuse of earthly wealth widens the gap between the rich and the
poor. Oppression of the poor by the rich will become the order of the day. In
social parlance, the situation brings about general underdevelopment since the
wealth of the nation is not well utilized.
