You are like salt for the
whole human race. But if salt loses its saltiness, there is no
way to make it salty again. It has become worthless, so it is
thrown out and people trample on it. You are like light for the
whole world. A city built on a hill cannot be hid, no one lights
a lamp and puts it under a bowl; instead it is put on the
lampstand, where it gives light for eveyone in the house. In the
same way your light must shine before people, so that they will
see the good things you do and praise your Father in heaven.
~Matthew 5:13-16
You do matter. Everything you do matters in your life. Do not let
anyone tell you otherwise. You are
loved.
